Volumetric Modulated Arc Therapy (VMAT)

Volumetric modulated arc therapy (VMAT) is a novel radiation therapy technique that delivers the radiation dose continuously as the treatment machine rotates. This technique accurately shapes the radiation dose to the tumour while minimising the dose to the organs surrounding the tumour.

VMAT works similarly to intensity-modulated radiation therapy (IMRT) in the way the radiation dose is varied throughout treatment.

What is VMAT used for?

VMAT is particularly useful for delivering radiation therapy to tumours near sensitive body organs, and can be an effective treatment for many types of cancer.

What does VMAT mean for you?

VMAT planning and treatment is technically demanding and requires a high level of precision. The VMAT procedure typically takes around 20 minutes, much like a three-dimensional conformal treatment. Most of this time is positioning you accurately. X-ray images are taken daily to check that everything is lining up as planned and then treatment can be given. VMAT uses the same type of radiation as other radiotherapy treatments.

The VMAT team

VMAT treatment is planned and delivered at three of our Peter Mac radiation therapy sites: Melbourne, Moorabbin and Sunshine.

A team of specialists are required to plan and deliver VMAT, including radiation oncologists, radiation therapists and medical physicists. You will also be supported by a range of other professionals including nurses and allied health practitioners. The Peter Mac radiation therapy team is proud to offer this treatment, and we are dedicated to developing and progressing treatment options for the people of Victoria.

Please speak with your doctor to determine if VMAT is the appropriate treatment choice for you.
