Volumetric modulated arc therapy [VMAT]

VMAT allows more difficult tumours, such as ones wrapped around other important structures, to be targeted precisely.

Overview

Volumetric modulated arc therapy [VMAT] involves the use of external radiation therapy beams being directed in a series of arcs or angles by a rotating machine to allow for greater access to a cancerous tumour.

This therapy reduces the likelihood of impacting healthy surrounding tissues, and allows more difficult tumours, such as ones wrapped around other important structures, to be targeted precisely.
