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.
