Tag: refurbished linear accelerators

Radiation therapy is just one treatment used in the treatment of cancer.  Linear accelerators, LINAC, are often used to deliver radiation which destroys cancerous cells.  LINAC machines use high energy x-rays to deliver radiation to cancerous tumors.  This breaks down and destroys the cancer cells while trying to minimize the damage and exposure to the surrounding healthy cells.  Radiation therapy is used to shrink and destroy cancer to prevent it from spreading. 

Radiation treatment can vary a great deal depending on the type of cancer and where it is located.  Linear accelerators are just one type of machine used to administer radiation.  When a patient is diagnosed with cancer, your oncologist will work with a team of experts to determine what type of treatment is best for you depending on your cancer, its location, overall health, and medical history. 

Keep in mind when a cancer treatment plan is being created that it may involve more than one type of treatment including radiation therapy, surgery, and/or drug therapy.  The best-known type of drug therapy is chemotherapy.  This is a medication that moves through the bloodstream in order to attack cancer in the body. 

Your team of doctors, including your oncologist will prescribe a treatment plan for your unique cancer.  Often this includes a combination of treatments.  When a combination of treatments is prescribed to treat cancer, it is important to follow the order that your doctor specifies as there often is a specific order that treatment needs to be given in order to treat specific conditions. 

Cancer is not the only medical condition that is treated using radiation therapy.  Below we will highlight different diseases that respond well with radiation therapy.

• Acoustic Neuroma

This is a tumor that is not cancerous.  It is produced when the body over produces Schwann cells.  When this occur the abundance of cells presses on the nerves that control hearing and balance within the inner ear. 

• Arteriovenous Malformations

This occurs when a connection between the arteries and veins in the brain and spine are atypical.  When this happens there will be neurologic symptoms and bleeding. 

• Bone Cancer

Bone cancer is a growth of abnormal cells in a bone.  These cells can either be cancerous or benign.

• Brain Tumor

Like bone cancer a brain tumor may be either cancerous or non-cancerous.  A brain tumor occurs when there is an irregular development of tissue in the brain. 

• Chondrosarcoma

This is a type of bone cancer that is malignant.  It most often is seen in the cartilage cells of the femur, arm, knee, pelvis, or spine.  Other areas that may be affected, but less often are areas like the ribs. 

• Chordoma

Chordoma is very rare.  It grows slower than most cancerous tumors that occur along the spine from the bottom of the skull all the way down to the tailbone.

• Ewing’s Sarcoma

This is a type of cancer that occur in soft tissue and bone.  It is often located in extremities and can involve muscles and soft tissue close to the site of a tumor.  It is also a cancer that spreads to areas throughout the body. 

• Leukemia

Leukemia is a type of blood cancer that develops in bone marrow.  This type of cancer produces three major blood cells including platelets, white and red blood cells.

• Meningioma

One type of tumor that cultivates from meninges, the protective membranes surrounding the brain and spinal cord is Meningioma.  This is often a benign and slow-growing tumor.

• Osteosarcoma

Most often occurring in children and young adults, this is a type of bone cancer that cultivates in the osteoblast cells which form the outer covering of bones.

• Soft Tissue Sarcomas

This rare cancer is just one of many soft tissue sarcomas.  Soft tissue sarcomas, overall, are rare.

• Trigeminal Neuralgia

This is a disorder in the nerves which causes pain in parts of the face that feel like a stabbing or electrical shock like pain.

There are two main types of radiation therapy that are used in treatment including external and internal radiation.  External radiation is delivered using a LINAC.  This is a machine that gives treatment outside of the body by moving around it without touching the patient.  External radiation using a linear accelerator causes patients no pain and cannot be felt during treatment. Internal radiation, brachytherapy, is radiation therapy that is used to treat certain gynecological and prostate cancers.

Information on linear accelerators, new and refurbished or parts for maintenance and repair can be found at https://www.acceletronics.com/ and https://radparts.com/.

There are many reasons that health care facilities look into purchasing refurbished linear accelerators verse new.  Most assume that refurbished medical equipment is purchased solely because it is more affordable than new however that is not the only reason to consider. 

Look into refurbished LINAC systems when:

• Treating fewer than ten patients a day

When medical facilities are not exclusively treating patients seeking radiation using a linear accelerator there may not be the funds to support the expense.  Health care centers that treat less than ten patients a day using a LINAC benefit from purchasing a refurbished system.  A previously owned, refurbished linear accelerator is less expensive and thus the monthly expense to lease/finance is lower.  What this means for your facility is that the payment is able to be covered by the few patients being treated daily.

• You live in a location where reimbursement rates are low

When a medical facility is located in an area where facilities need to be profitable to continue running and compensation rates are low it is important to keep expenses low.  Public clinics don’t need to worry about being lucrative however that is not the same for all health care facilities. 

• There is not a need for the latest technologies

When a medical facility is using a LINAC system and only requires partial use of its technologies then a refurbished linear accelerator is a perfect choice.  Many veterinarians choose to purchase refurbished linear accelerators to treat pets and animals.  They don’t require all the bells and whistles found in new radiation so refurbished equipment makes sense. 

• You are just starting out

When a medical facility is just opening, they may not have the revenue base to purchase more expensive medical equipment with the newest technologies.  Healthcare facilities that are looking to upgrade to new technology in four to seven years but need to treat patients and generate funds benefit from purchasing refurbished medical equipment.  Health care centers often want to buy brand new equipment when starting out, but it is a huge risk to invest capital that is not guaranteed in such expenses.  Pre-owned, refurbished LINAC help to mitigate the risks while allowing facilities to effectively treat patients.

• The facility needs to move locations

When a medical facility has one linear accelerator but intends to move locations and are unable to have down-time the purchase of a refurbished machine is a good idea. Linear accelerator relocation can take upwards of four weeks so many facilities choose to purchase an identical machine to install at the new center.  When the move has been completed the equipment can be sold or kept as a backup.

• A backup machine is desired

When a medical facility wants to ensure they are always able to treat their patients a back up linear accelerator is necessary.  This is often the case when a facility has a large patient load.  When the main LINAC is down for maintenance or repair patients can still be treated using a back up machine.  Refurbished linear accelerators are a great backup solution.

There are several questions that come along with a cancer diagnosis. One of the first questions that patients ask is regarding the treatment of their newly diagnosed cancer.  Patients want to know how they are going to rid their body of cancer.  The answer most often, external radiotherapy.

External radiation, radiotherapy is treatment of cancer using a machine known as a linear accelerator to directly aim radiation beams to the cancerous tumors from outside the body.  These beams are meant to shrink and/or destroy the cancerous tumor without harming the healthy tissue surrounding it.  This is different from internal radiotherapy where radiation is delivered to the cancerous tumor within the body.

Radiotherapy works through a process of damaging the DNA that exists within the cancer cells.  A patient’s personal DNA, which is genetic, is the code that controls how a patient’s body will behave during treatment.

Before a patient starts treatment their team of experts will create a plan and introduce it to the patient.  It will include several elements including the short and long terms side effects of radiation.  Most side effects are short terms and will disappear with medication and time. 

Radiation therapy begins with a wide range of tests.  These often include:

• X-Rays
• CT Scans
• MRI’s
• PET Scans

These scans and images will allow experts to develop a treatment plan that allows the highest dose of radiation to the cancer while trying to reduce the effects to the healthy tissues surrounding it.

When you are set to receive external radiotherapy you will have treatment in a radiotherapy department.  Radiotherapy machines are large and can vary.  The most common machine in delivering radiation is known as a linear accelerator, LINAC.  A linear accelerator uses an electricity to create the beams of radiation.  Patients will not feel the radiation that a LINAC gives off. There are possible side effects however these are rare. 

Radiation therapy works because it can treat the cancerous cells and the bordering healthy tissues without harm.  A high dose of therapy is given directly to the cancer and lower dose to the surrounding tissues.

Radiation is delivered in individual fractions that are smaller than the full dose.  This ensures that the healthy cells surrounding the cancer to recover between treatments.  Patients will have what is known as a series of smaller dose treatments which is known as radiotherapy fractions.

Radiotherapy is intended to relieve the symptoms of cancer including pain.  This is known as a type of palliative radiotherapy, fewer fractions and sometimes just one.  The radiotherapy dose with each radiotherapy fraction is larger but there are fewer fractions.  Overall the radiotherapy dose is lower.  Palliative treatment has a decrease in side effects and is used as a cure for cancer.

There is a lot of information on radiation therapy online.  The process of delivering radiation isn’t exactly the same between facilities however it’s similar.  In this installment we will look into radiation therapy generically to provide a general overview. 

Methods For Treatment

There are a number of ways to treat cancer with radiation; the method used depends on the nature and position of your cancer.  The most prevalent method of radiation is known as external beam therapy.  This is often done using a linear accelerator from the outside of the body directing radiation to the tumor. 

Radiation therapy is known to affect both cancerous and normal cells.  Radiation has a greater effect on cancerous cells.  Treatment is given at the highest dose possible, within a safe limit, to kill cancerous cells without causing damage to normal, healthy cells.  If the goal is to reduce the size of the tumor in order to relieve symptoms or to shrink the tumor for surgery, low dosages are often used.

Radiation Professionals

Radiation therapy is planned out by a specialist cancer doctor known as a radiation oncologist.  Then radiation is delivered by a radiation therapist.  A team of specialists including nurses, health care assistants, counselors, and dieticians will work together to ensure the best possible outcome for your treatment. 

There are many benefits included in how radiation treatment is planned.  Each patient has a unique treatment plan that is designed to meet each patient’s particular need.  During the initial visit a course of treatment will be planned.  This is done using simulators, x-rays, and scans to pinpoint the tumor.  The skin will be marked to define the treatment area. 

Life With Treatments

Most individuals receiving radiation therapy will not need to stay overnight in a hospital after receiving radiation.  Therapy is done on an outpatient need unless your radiation oncologist determines that treatment would be more effective if done while admitted.

Patients are allowed to continue life as normal during their radiation treatment.  It should not cause too much interruption to your day, in fact it should be looked at as another daily routine activity.  Radiation is given using a linear accelerator which works by delivering radiation from the outside through your skin.  Patients receiving treatment lay on a treatment couch and are asked to remain completely still.

Radiation oncologists will determine the length of treatment needed when first evaluating your situation.  The course of treatment can last anywhere from a week to six and can be performed on a weekly or daily basis.  This will depend on a number of factors including the area that is being treated, the aim of the treatment, and more. Each session of radiation varies depending on the machine used.  Most sessions last between five and fifteen minutes.

A drive stand is a large part of a linear accelerator.  It is a cabinet in the shape of a rectangle that is attached to the floor within the treatment room.  The horizontal axis bearings that the gantry rotates on are positioned within the drive stand.

Components Within the Drive Stand

• Klystron or Magnetron
• RF Waveguide
• Circulator
• Cooling Water System

Klystron:

A Klystron is responsible for the microwave power that is used to accelerator the electrons.  This process occurs through intensification of present RF (Radio Frequency) electromagnetic waves.  The basic description of the operation of a Klystron is that it is a RF amplifier. A Klystron is often chosen for LINAC needing larger amounts of electron energy.

Magnetron:

A magnetron can be used in place of a Klystron.  A Magnetron is an electron tube that is responsible for providing the microwave power to accelerator electrons. A Magnetron is often chosen for LINAC needing smaller amounts of electron energy such as 4 MeV to 6 MeV LINAC.

RF Waveguide:

The structure in which the microwave powered RF electromagnetic waves are accelerated from the Klystron or Magnetron.

Circulator:

The circulator connects the Klystron or Magnetron to the RF Waveguide.

Cooling Water System:

A cooling system is in place to prevent overheating.  It creates a stable temperature environment within the Drive Stand and Gantry.

A gantry rotates three hundred and sixty degrees around a single point.  It works by directing the radiation beam from the LINAC to the tumor without moving the patient. 

Components Within the Gantry

• Electron Gun
• Accelerator Structure
• Treatment Head

Treatment Head:

The treatment head of a linear accelerator encompass the components that shape and monitor the radiation beam.  These components include bending magnet, collimator, ion chambers, tray slots, wedges, blocks, and compensators.

Modulator Cabinet:

The modulator cabinet is the loudest components of a linear accelerator.  This component is located within the radiation treatment room.  The modulator cabinet includes a fan control, auxiliary power distribution system, and a primary power distribution system.  The fan control is used to cool off the power distribution systems.  The power distribution systems include the emergency off button to shut down the power to the LINAC.

Bending Magnet:

A bending magnet is a component of a LINAC that changes the direction of the beam down towards the patient.  It bends the beam towards the target and produces different paths for the beam for different energy needs.

With todays technology treating cancer through radiation therapy is completely customized to each specific patient’s need.  Linear accelerators deliver cutting-edge radiation therapy; providing one of the most advanced cancer treatment techniques available.  Linear accelerators are able to deliver targeted radiation beams directly onto a patient’s cancerous growths with minimal damage to the healthy surrounding tissue. 

Oncologists often recommend radiation therapy using linear accelerator technology to treat new cancer diagnosis as it often improves the chance of a good outcome. Below are a number of the benefits that cancer patients find that LINAC offer in cancer treatment.

Personalized Care

Using detailed imagery linear accelerators pinpoint cancerous tumors with amazing precision.  This technique is known as image-guided radiation therapy.  Treatment with LINAC allows for radiologists to compensate for the shrinkage of the tumor and its movement.   Radiation therapists will treat tumors individually before each treatment session to account for the varying size and shape of the tumor and its changing position in the body.  This allows them to directly deliver radiation to the cancerous cells to shrink and destroy them.  Technicians can target cancer more accurately which decreases the risk to healthy tissue. 

Treatment to Any Part of The Body

Cancer can grow in any part of your body.  Thankfully, linear accelerators are able to treat them wherever they are.  Radiation therapy, using linear accelerators allows for the targeting of cancerous growths no matter where they are including: prostate, uterus, cervix, and/or prostate.

Higher Cure Rates

With the advanced technology in treating cancer that linear accelerators offer, specialists are able to monitor and adjust for shrinking tumors on a daily basis.  This means that each treatment is aimed more directly at the cancerous tumor which increases the effectiveness of the treatment and encourages a higher cure rate. 

Increased Comfort in Treatment

Treating cancer can seem incredible scary.  Treatment sessions can be long and uncomfortable but thankfully treating cancer with linear accelerators makes radiation sessions faster and more comfortable.  LINAC treatment sessions which may have lasted 10 to 30 minutes can now be completed in less than two minutes.  Quicker treatments make more patients less anxious and more comfortable.  

It is easy to see how LINAC improve the treatment of cancer.  Linear accelerators make cancer treatment faster, increase cure rates, and can be customized to each individual’s patients needs.  Radiation therapist plans develop personalized treatment plans that include education and support.

Purchasing a linear accelerator takes a great deal of planning, an experienced team to pull it all together, and a commitment to purchasing a quality piece of equipment.  The planning process, as previously stated includes:

• Understanding the goals of your clinic
• Facility Planning
• Schedule
• Budget

In this installment we will look at the team of experts that you will need as you go about purchasing and implementing treatment using a large scaled piece of radiation therapy equipment such as a LINAC.  Putting an experienced team of experts in place starts by involving individuals who share a similar vision for the facilities project.  A unified group of professionals who will communicate with one another throughout the project.  This team should include: vault designer/construction, provider of the LINAC, physics support, IT team, and the facilities clinical team for implementation.  Choosing the best players for your team ensures success.  It is your responsibility when making a purchase of this magnitude to perform due diligence every step of the way.

Vault Designer/Construction

Only a specialist can design and construct a vault that is capable of safely accommodating a linear accelerator.  Not every construction company can create this safe space, it requires experience.  Having a reliable company, with proven results in your corner will not only save you money but also critical time as you begin planning the installation of your linear accelerator.

Linear Accelerator Provider

Not all LINAC and radiation therapy equipment providers are the same.  Don’t purchase equipment based solely on the basis of price as this is not the true cost of owning a linear accelerator.  It is crucial, whether you are purchasing a new, refurbished, or used linear accelerator that you work with a company that provides the necessary specialized installation and support needed throughout the ownership of the equipment.  Vendors such as Accelectronics, that can complete sales, delivery, installation, servicing, replacement parts, and removal provide reliability and accountability that many companies cannot compete with. 

Physics Support

Successful treatment and patient outcomes only can occur when a continuous quality assurance program is in place.  This group must have the tools and knowledge needed to make sure the installation and implementation of said equipment in your facility will be successful.  This can include but is not limited to the assurance that you are offering the best possible treatment, to ongoing FAQ support.

IT Team

The hardware and software of all types of medical equipment is ever changing, the same is true of radiation therapy equipment such as linear accelerators and CT scanners.  An IT team must be in place to ensure that equipment is kept up to date with the latest upgrades.  They also must understand the overall impact to the facility a new piece of equipment such as a LINAC will have.  Different systems must work together.  It is up to your IT team to implement this network in order to have successful patient outcomes.

Implementation

Once the other pieces of the puzzle are in place including technology, the clinical implementation team will work together to ensure the best treatment plans are delivered to patients. This team includes: in-house therapists, physicists, and dosimetrists.  This team is in place to guarantee an optimization treatment from beginning to end.

There are several common types of radiation therapy that are used in treating cancer today.  Radiation therapy is classified according to the type of radiation particles or waves that are used in treatment which include: photons, electrons, or protons.  The most commonly available treatments using photons and electrons.  In this installment we will look further into treatments using linear accelerators, LINAC, and CT Scanners, in the treatment of cancerous tumors.

3D Conformal Radiation Therapy

3D conformal radiation therapy is a method of treating cancer that uses CT imaging, Cat scan-based, in the treatment of cancerous tumors.  In 3D conformal radiation therapy, the tumors and organs are well-defined 3D images as opposed to flat images that are gotten from x-rays.  Tumors are outlined in three dimensions on a CT scan. Healthy organs are defined as well when scans are performed so that technicians can see areas that need to be avoided. 

Radiation beams are then organized in the best possible way to avoid healthy organs while delivering the highest dose of radiation possible to the cancerous tumor.  Patients are placed in the same position as they were when their CT scan was performed.  This allows for accurate placement of beams according to the scans that were obtained. 

Special software is used that calculates the total amount of radiation that will be delivered to the tumor and normal tissues to assure that the tumor is sufficiently covered in radiation while healthy tissues and organs receive as little radiation as possible.   The radiation beams are adjusted even further based on the software’s calculations to give healthy doses of radiation while being manipulated into varying positions and shapes as defined by the tumor.  Radiation beams are directed using one of two types of machines: Cerrobend blocks or multi-leaf collimators. 

Cerrobend blocks are individually shaped to form specific, custom-made shapes that create the correct beam for treatment.

Multi-leaf collimators are skinny, metal blocks that move independent of one another in a quick, swift manner to form complex patterns to shape radiation treatment beams.  They are commonly used in IMRT.

Intensity Modulated Radiation Therapy (IMRT)

IMRT is another form of delivering photons in the treatment of cancerous tumors with the possibility of lowering the dose of radiation delivered to non-cancerous tissues.  Planning for IMRT begins in a similar fashion as 3D conformal radiation therapy in that it starts out with simulation.  The tumor and organs are all outlined and shown as three-dimensional objects. Several beams of radiation are situated at varying points around the person in order to deliver the optimal amount of radiation. In IMRT, the beams are divided into a grid pattern.  The large radiation beam is split into numerous smaller beams known as beamlets. 

Software is used to establish the appropriate pattern to break the beamlets down into from the larger beam to prevent radiation targeting healthy tissues while delivering the optimum radiation to the cancer.  The multi-leaf collimators often form more than fifty different shapes during radiation treatment.  The main advantage to this type of radiation therapy is that the patterns the beamlets form are precise and the radiation controlled.  IMRT is often utilized when cancerous tumors are in positions that are difficult to treat. 

Often tumors that are directly adjacent to or wrapped around normal healthy organs, IMRT is used.  Intensity modulated radiation therapy reshapes the radiation in the best possible way to avoid normal organs while delivering large doses of radiation to the tumor.  IMRT is used commonly in the treatment of head and neck tumors where there are many other significant structures and organs that are near the tumor such as the spinal cord.

The one downside to IMRT is that it can take longer to plan and deliver treatment than other 3D conformal therapy.  Radiation can also be a bit more uneven as well because of the small beamlets that are being used.  Although normal organs are out of danger of high doses of radiation larger number of normal organs receive low doses of radiation which can be a disadvantage.  As of today, low doses of exposure to radiation are unknown.  Tumors must continually be monitored for movement and shrinkage to ensure that radiation is being delivered to the cancer.

Brachytherapy is a type of radiation therapy.  Unlike other types where an external radiation machine known as a linear accelerator is used brachytherapy uses radiation that is implanted close to the cancerous cells. In brachytherapy radiation is implanted within your body as close to the cancerous cells as possible.  A higher dose of radiation therapy can be given in a shorter amount of time than with types of external radiation therapy.

Brachytherapy is not delivered through external radiation therapy but instead the radioactive materials are delivered using a hollow tube(catheter).  The radioactive materials are implanted directly onto the cancerous tumor.  The implants that are used can be either temporary or permanent. This form of radiation therapy allows treatment to be delivered to the cancer cells without damaging the normal tissues close to the cancer. 

Doctors use brachytherapy when they have decided that your best treatment option is a higher dose of radiation delivered directly to the cancer.  External radiation offers lower doses of radiation than brachytherapy can. Higher doses of radiation are often needed for cancers such as: brain,breast, cervical, ovarian, head, neck, and lung. 

How does implantation work?

Implantation of the radiation can be delivered in two ways:through an outpatient procedure or another which requires general or local anesthesia and a stay at the hospital.   

How much time is needed for brachytherapy?

 The time needed to perform brachytherapy depends on whether it is being done on an inpatient or outpatient basis, the type of radiation therapy to be used, and the nature of your cancer.  Internal radiation therapy can be done through the course of three to five treatments when done on an outpatient basis for a few minutes over a number of days while other types of internal radiation therapy is left in place for up to a week and requires a hospital stay during this period of time.

Should side effects be expected?

Although you will most likely avoid side effects during treatment you may feel some discomfort. Having a catheter put in place can cause tenderness.  If you are given anesthesia when the catheter is implanted you can feel nauseous, weak, and drowsy.  Medicine can be prescribed that allow you to relax while relieving your pain.  If you experience any burning, excess sweating, or any other symptoms that seem unusual to your physician.

What happens when the actual implant is removed?

After the implant is removed the surrounding area can become sensitive for a bit although regular activity can be resumed when you feel ready.  As with any procedure it is important to allow your body to rest, so you can fully recover after treatment.

If you have a permanent implant installed rest assured, it will safely stay in place.  Once the radiation is completely gone the capsule in which it is contained will become inactive and no longer providing radiation.
