Vmat Radiation Therapy
During each rotation the cone beam is continuously shaped or modulated by the multi leaf collimator. Each rotation is called an arc and one or more arcs might be used.

However sbrt treatments can take several hours to complete while vmat can take several minutes as in the case of external beam therapies.
Vmat radiation therapy. Vmat today and tomorrow. Vmat delivers radiation by rotating the radiation machine through one or more arcs while radiation is continuously delivered. Volumetric modulated arc therapy vmat is a type of specialized intensity modulated radiation therapy.
Volumetric modulated arc therapy vmat is a novel radiation therapy technique that delivers the radiation dose continuously as the treatment machine rotates. The machine continuously reshapes and changes the intensity of the radiation beam as it moves around the body. Mehta and his colleagues have begun using vmat for stereotactic body radiation therapy sbrt and he finds the vmat plans are comparable to traditional sbrt plans.
This technique accurately shapes the radiation dose to the tumour while minimising the dose to the organs surrounding the tumour. Vmat faster treatments and lower radiation dose to you. Each rotation is called an arc and one or more arcs might be used.
The specificity of this technique is to modify three parameters during the treatment. Each volumetric modulated arc therapy vmat treatment is completed in less than two minutes. Volumetric modulated arc therapy vmat is a novel radiation technique which can achieve highly conformal dose distributions with improved target volume coverage and sparing of normal tissues compared with conventional radiotherapy techniques.
Volumetric modulated arc therapy vmat focuses the radiation on the tumor while protecting healthy tissues. Vmat can also be called rapid arc. Volumetric modulated arc therapy vmat delivers radiation on a linear accelerator using a cone beam that continuously rotates around the patient.
In vmat as the linear accelerator rotates around you radiation beams sweep in continuous. During each rotation the cone beam is continuously shaped or modulated by the multi leaf collimator. Volumetric modulated arc therapy vmat is a new radiation therapy technique that allows our team to deliver more tightly focused treatments to your cancer in a significantly shorter time.
Vmat stands for volumetric arc therapy. Vmat is different to normal imrt in that the radiotherapy machine rotates around the patient during a radiotherapy beam in an arc shape. In addition the dose rate how much radiation delivered for.
Volumetric modulated arc therapy vmat volumetric modulated arc therapy vmat is a radiation technique introduced in 2007 which can achieve highly conformal dose distributions on target volume coverage and sparing of normal tissues. Vmat allows doctors to treat complex cancers while minimizing exposure to surrounding healthy tissue. Faster treatments improve the accuracy of radiation delivery in addition to improving patient convenience and quality of life.
