A particle therapy apparatus configured to scan a charged particle beam over a target according to a pre-defined treatment field which covers a treatment surface in an isocenter plane of the apparatus. The apparatus is capable of scanning the beam over a reachable surface which covers and is larger than the treatment surface. A beam stopper is arranged downstream of the scanning magnets of the apparatus, at a position to prevent the beam from reaching at least a portion of the reachable surface and to allow the beam to reach any portion of the treatment surface. A control system is configured to control the apparatus to direct the beam to the beam stopper and to meanwhile measure a position of the beam, to calculate a difference between a desired position and the measured position of the beam when directed to the beam stopper, and to scan the beam over the target according to the pre-defined treatment field by taking into account the calculated difference.

Device and method for tuning a charged particle beam position

A method for assessing a quality of a beam shaping device includes, establishing with a treatment planning system (TPS) the planned device design of the beam shaping device, manufacturing the beam shaping device according to the planned device design, establishing a CT-scan of the beam shaping device to yield an actual CT-image, determining dimensions and local materials densities from the actual CT-image, determining a calculated dose distribution in the treatment volume (V), and comparing the calculated dose distribution (cDD) with a reference dose distribution (rDD).

Off line quality control of a beam shaping device for radiation therapy

The invention is related to a method for monitoring a range of a particle beam in a target. The method is using gamma detectors for detecting prompt gammas produced in the target. The time differences between the time of detecting a gamma quantum and a time of emission of a particle or a bunch of particles from the radiation device are determined. A statistical distribution of those time difference is used to deduce information related to the range of the beam. The invention is also related to an apparatus for monitoring a range based on measured time profiles of detected prompt gammas.
