Volumetric modulated arc therapy (VMAT)

Volumetric modulated arc therapy (VMAT) is a modern form of Intensity-modulated radiation therapy (IMRT), which provides an accurate distribution of the radiation dose calculated and presented in 3D format, as the gantry (scanning scanner system) rotates around patient. The dose rate of radiation, the size and shape of the irradiation field, as well as the speed of rotation can be adjusted during the therapy session.

Thanks to the use of special software and modern linear accelerator, it is possible to improve the uniformity of the dose distribution and, at the same time, significantly reduce the treatment time compared to IMRT (up to eight times). The duration of rotation / irradiation is usually less than two minutes. A short treatment time is optimal for patients who, due to severe pain, cannot lie in the supine position for a long time.

Like IMRT, VMAT is used, in particular, when it is necessary to irradiate large areas of the body with uneven boundaries. With the help of this modern irradiation technology, it is possible to safely and efficiently treat tumors located in close proximity to vital organs and without fear of damage to these organs by high doses of radiation. For example, when the prostate, rectum and tumors of the female reproductive system are irradiated, the intestine and bladder can be better protected, and when the head, neck, spinal cord and salivary glands are irradiated, it is better to protect the optic nerves and the brain stem.
