A linear accelerator is one of the best tools to use for eradicating tumors in a cancer patient. In the past, one of the problems with cancer treatment was that healthy normal cells were killed too. But with a LINAC, linear accelerator, this machine delivers elevated electrons or energy x-rays that conform to the tumor’s form. It focuses on destroying cancer cells while sparing the surrounding normal tissues.
LINAC systems also contain numerous incorporated measures of protection that will ensure that they only deliver the most accurate dosage to patients. Therefore, servicing linear accelerators is an extremely valuable part of the entire process, as well as requiring constant checking by a medical physicist to ensure that they continue working properly.
Before a Procedure Begins
A patient who has been scheduled for radiation therapy with a LINAC will undergo a long and stringent process to ensure accuracy and safety. This begins with an appointment with the radiation oncologist. The oncologist will then collaborate with the radiation dosimetrist and a medical physicist to develop the best treatment plan. Before treatment proceeds, the patient’s own doctor will review and double check this plan before it can begin.
There will also be quality assurance procedures put in place to ensure that the patient remains safe during the procedure. These procedures are also put in place so that if multiple treatments are required, that the patient will receive each one in the exact same manner.
A LINAC is most frequently used for external radiation beam treatment for patients with cancer. Linear accelerators treat all parts and organs of the body and the organs that may have cancer. The machine delivers high-energy x-rays or electrons to the center of the patient’s tumor. It destroys the cancer cells while sparing surrounding tissue.
How a LINAC Works
The LINAC uses a microwave technology that is like radar technology. It accelerates electrons so that they collide with a heavy metal target that produces high energy x-rays. These are shaped to conform to the exact shape of the patient’s tumor.
The patient lies on a movable couch during treatment. The patient must be in the right position for the most effective treatment. The couch can be moved up, down, left, right, and left in and out. The beam is directed from a gantry which is rotated around the patient.
There are a variety of experts who operate this equipment. It’s important that the LINAC be regularly serviced. There are qualified businesses who perform regular servicing of linear accelerators.
Repairs May Be Needed On LINAC Systems
In some instances, the LINAC may need to be repaired. The machine will deliver errors and reports and not turn on if it’s not safe. This is when clinics and hospitals need to call in technicians for repairing LINAC systems. It can be difficult to determine what has gone wrong, as the LINAC system is complex. It may simply need servicing, or it may need certain parts replaced.
