Varian intensity modulation proton therapy (IMPT) uses dynamic peak technology to enable clinicians to customise and maximise the radiation dose to a tumour, while delivering lower global doses to healthy tissue.
This technology makes it easier for targeting tumours with complex shapes, or tumours that wrap around critical structures such as the spinal cord.
Irradiations from multiple angles are combined in an optimal manner to improve control of dose distributions.
Scanning beam technology also eliminates the time-consuming need to manually insert separate shaping accessories for each beam angle in order to match the beam to the shape of the tumour.
