Abstract
A charged hadron therapy system for delivering charged hadron radiation to a target is provided. The system comprises a target positioning couch for supporting the target being moveable along a translation direction and a beam delivery system comprising a beam scanning means for scanning a hadron pencil beam over said target in a first scanning direction and a second scanning direction being substantially parallel with the translation direction. The beam scanning means is limited for providing a maximum scanning amplitude AY in the second scanning direction. The system comprises an irradiation controller configured for simultaneously and synchronously performing the moving of the couch and the scanning, so as to deliver charged hadron radiation to a target over a target size being larger in the Y direction than the maximum scanning amplitude AY.
