Claim Text:
1. A charged hadron therapy system for delivering charged hadron radiation to a target, the system comprising: a target positioning couch for supporting said target, the target positioning couch being configured for moving along a translation direction, a beam delivery system comprising a beam scanning means for scanning a hadron pencil beam over said target in an first scanning direction and a second scanning direction, the second scanning direction being substantially parallel with the translation direction wherein the beam scanning means is limited for providing a maximum scanning amplitude AY in the second scanning direction, and an irradiation controller configured for simultaneously moving the couch along said translation direction and scanning the hadron pencil beam in X and Y in a synchronized manner, 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.
