Trilogy Linear Accelerator WVU Healthcare cancer specialists have expanded our cancer fighting capability with the addition of a Trilogy linear accelerator. A linear accelerator delivers external beam radiation treatment for cancer, delivering high-energy x-rays to the tumor without damaging surrounding tissue. The tumor can be treated from any angle by rotating the machine or treatment bed. Treatment times are shorter, making the treatment more comfortable for the patient. Equipped with a new image guidance system, this new device allows the radiation oncologist to see the tumor in real time for the most accurate treatment. The new device also uses stereotactic body irradiation – a precise, high dose form of radiation that enables a shorter overall treatment time. Treating lung cancer with standard radiation might take five or six weeks to treat. But, with this targeted form of radiation, we can complete the cancer treatment in one or two weeks.
