Volumetric Modulated Arc Therapy

VMAT is a novel radiation therapy technique which delivers the radiation dose continuously while the treatment machine rotates. VMAT precisely shapes the radiation dose to the tumour and minimizes the dose to the organs around the tumour.

Volumetric Modulated Arc Therapy works like IMRT in the way the radiation dose is varied in the entire treatment. This treatment is especially useful to deliver radiation therapy to tumours near a patient’s sensitive body organs.

The planning and treatment are technically demanding and it requires a high level of accuracy. Typically, the VMAT procedure takes around 20 minutes, similar to a 3D CT. Most of the time will go for positioning a patient accurately. Also, the X-ray images are taken every day to check that everything is lining up as planned to initiate the treatment. This therapy also uses the same type of radiation as other radiotherapy treatments.

VMAT delivers accurate and fast treatment, thus, it reduces the number of patient visits and improves the recovery time. Also, it allows tumors to be treated which are near critical structures in a patient’s body. In some cases where a tumour is wrapped around an organ, this treatment can precisely target the tumour and minimize the damage to the organ

VMAT is particularly useful for treating cancers often in delicate areas like breast, lung, and prostate.
