Volumetric Modulated Arc Radiotherapy

Technology such as Volumetric Modulated Arc Therapy (VMAT) system keeps Iredell Memorial’s Radiation Therapy Center on the cutting edge of cancerous tumor treatment.

The main advantages of Volumetric Modulated Arc Therapy (VMAT) are precision and speed. Volumetric Modulated Arc Therapy (VMAT) focuses the radiation on the tumor while protecting healthy tissues. Each Volumetric Modulated Arc Therapy (VMAT) treatment is completed in less than two minutes. Faster treatments improve the accuracy of radiation delivery, in addition to improving patient convenience and quality of life.

Volumetric Modulated Arc Therapy (VMAT) uses photons (W-rays) generated by a medical linear accelerator. Very small beams with varying intensities are aimed at a tumor and then rotated 360 degrees around the patient. This results in attacking the target in a complete three-dimensional manner. VMAT beams can be as small as 2.5 x 5 millimeters. That’s the size of a pencil tip! The idea is to deliver the maximum dose of radiation to the cancerous tumor while reducing the amount of healthy tissue effected. During the course of a single 360 rotation by our state of the art Varian True Beam linear accelerator, a complete treatment is delivered.

At Iredell Health System’s Radiation Therapy Center, our first priority is patient care. That’s why we continue to offer our patients the most advanced technologies available in the treatment of their disease. Volumetric Modulated Arc Therapy (VMAT) technology represents another step in the fulfillment of our ongoing mission.
