Volumetric-Modulated Arc Therapy (VMAT) / RapidArcTM
Volumetric-Modulated Arc Therapy (VMAT) is a newer form of IMRT that delivers external beam radiotherapy through a continually rotating radiation source that encircles the patient.
It makes changes in the speed of rotation, the shape of the radiation field and the strength of radiation. This results in the faster delivery of precisely targeted radiation doses.
VMAT in the form of RapidArc is currently available in the St. James and Beaumont centres.
