What is VMAT?
Volumetric modulated arc therapy (VMAT) is a type of IMRT. It is sometimes called RapidArc©, depending on the manufacturer of the equipment.
It is very accurate and maximises the radiation dose to the tumour while minimising the overall dose as well as exposure to surrounding healthy tissue.
VMAT works by delivering a continuous beam of radiotherapy in an arc which moves around the tumour, changing the beam shape and treatment dose automatically as it moves.
Treatment sessions with VMAT are much shorter - usually between just two to four minutes.
All GenesisCare centres in the UK offer VMAT technology.
