RapidArc Radiotherapy technology is an enhancement on many of the Varian linear accelerators (radiation delivery platforms). It provides a very precise radiation therapy treatment often in less than two minutes, while maintaining the accuracy of the treatment and comfort of the patient. Treatment times are significantly faster than with most other linear accelerators. Treatment speed is important because it reduces the amount of time that you must lie still and avoid movement.
Before each treatment, robotic arms extend and the linear accelerator rotates around you to create a three-dimensional picture to confirm the location of the tumor. RapidArc® technology then provides a precisely sculpted 3D radiation dose as it rotates 360º around you.
