Toshiba Heavy Ion Therapy System

The rotating gantry treatment room irradiates target with Heavy ion beam from any angle by turning the irradiation nozzle. The X-ray imaging device is equiped for patient positioning, and it also works for respiratory-gated irradiation system.

The 3D scanning irradiation for Heavy ion therapy developed by Toshiba is a method which irradiates tumors as if a thin pencil beam quickly coated the target. This method allows us to not only respond to complex-shaped tumors but also perform high-precision and efficient irradiation.

Cases of organs that move along with respiration, such as lung, liver, and pancreas are common in radiothrapy. Combining the respiratory-gated irradiation technology with real-time target images by the obligue X-ray imaging and the rescanning technology, Toshiba has realized fast and accurate irradiation with uniform dose on moving organs as well.

Toshiba has equipped its system with an automatic positioning system designed to improve throughput and reduce the burden on medical staff. With just one X-ray exposure, the software corrects any deviation from the reference image. After correction, position verification is easily performed using intuitive mouse controls.
