Linear Accelerator

About Our Linear Accelerator

At the heart of every radiation oncology program is a sophisticated medical device called a linear accelerator or LINAC. The Dr. James and JoAnn Bourland Radiation Oncology Center will have one of the most advanced medical linear accelerators available today — the Varian Medical Systems TrueBeam.

This TrueBeam system will provide the state of the art in high precision, image-guided radiotherapy to treat tumors in various parts of the body.

How It Works

Linear accelerators send a guided beam of energy such as electrons or x-rays through the body and into cancer tumors. Directed by an array of advanced imaging devices and specialized software, the TrueBeam system delivers precisely measured energy to the exact dimensions and location of each tumor. In this way, diseased cells are eliminated while surrounding healthy tissue is protected.

Innovative Imaging

The system is equipped with a treatment table allowing almost infinite adjustment. This enables a higher degree of accuracy by allowing the table to move in all directions to align the treatment target.

A motion management interface (MMI) enables respiratory gating, a technique that tracks a patient’s normal respiratory cycle and adjusts the radiation beam as needed during treatment.

The TrueBeam system also contains an entire suite of Cone-Beam Computed Tomography (CBCT) imaging systems. This capability, combined with intelligent tools such as RapidArc® radiotherapy, will enable GVMH to offer a wide range of radiation treatment options for cancer patients.

A Shorter Course of Treatment

Radiation oncology is a vital part of modern cancer management plans. One of the benefits of our TrueBeam radiotherapy system is that it can help patients to heal in fewer sessions, which lowers the risk of side effects. In addition, treatment can be customized in real-time during radiotherapy by dynamic imaging enabled by the 2D, 3D, and 4D imaging capabilities of the TrueBeam system.
