The Swiss proton therapy facility at PSI: A compact isocentric gantry using spot scanning
- Paul Scherrer Inst., Villigen-PSI (Switzerland)
A new proton therapy facility is presently being commissioned at PSI. The application of the dose to the patient will be performed by rapid scanning of the focused proton beam in three dimensions under complete computer control (the so-called spot scanning technique, with a superposition of individually controlled Bragg peak spots at a rate of about 5000 spots/minute), using multiple fields on a compact isocentric proton gantry. The PSI proton gantry will be the second and most compact proton gantry in the world (4m diameter). The spot scanning technique is expected to provide automated 3d-dose conformation to the target volume on a routine basis without the need for patient specific hardware like collimators, compensators and range-shifter-wheels. The medical program, planned to start in 1995, aims at the introduction of new indications for proton therapy, including especially large and/or irregularly shaped tumors. The project should show the feasibility of a new and efficient approach to proton therapy as a first step toward its introduction in the hospitals.
