Abstract: A system and a method improve a quality of beam delivery in proton therapy by pencil beam scanning of a predeterminable volume within a patient that minimizes beam position errors. The system has a proton source generating a proton beam, a number of proton beam bending/focusing units, a beam nozzle having an outlet for the proton beam to penetrate the predetermined volume, a beam bending magnet, and a couple of sweeper magnets to sweep the proton beam in both lateral directions. A position-sensitive detector is aligned with the nozzle to control the position of the proton beam and control logic controls the position and the energy of the proton beam and has a beam steering data set. A correction logic is aligned with the control logic for correcting beam position errors by comparing an expected beam position with the actual beam position detected and generates beam position correction data.

Abstract: A system for an intensity-modulated proton therapy of a predetermined target volume within an object includes a proton source to generate a proton beam, a number of proton beam forming units and a beam nozzle having an outlet for the proton beam to penetrate the predetermined target volume of the object, thereby defining a cross sectional scanning exit area. The system includes further a beam bending magnet disposed upstream of the nozzle, and an x-ray tube and an x-ray imager. The x-ray tube is associated with an irradiation channel within the beam bending magnet, wherein the irradiation channel is oriented along the prolongation of the nominal proton beam direction thereby delivering the x-ray beam along the proton beam direction.

Abstract: A process for an intensity-modulated proton therapy of a predetermined volume within an object includes discretising the predetermined volume into a number of iso-energy layers each corresponding to a determined energy of the proton beam. A final target dose distribution is determined for each iso-energy layer. The final target dose distribution or at least a predetermined part of this final target dose distribution is applied by parallel beam scanning by controlling the respective beam sweepers, thereby scanning one iso-energy layer after the other using an intensity-modulated proton beam while scanning a predetermined iso-energy layer.

Abstract: An apparatus for carrying out proton therapy on a patient comprises a proton beam guiding device using magnets, quadrupoles, and an end-mounted device for proton beam guiding and control device with an exit window for guiding or directing the proton beam to the treatment spot in the patient. A patient table of the apparatus can be moved in a controlled manner in such a way that the patient can be placed in a desired position with respect to the proton beam. The proton beam guiding and controlling device can be turnably or rotatably mounted around a horizontal axis of rotation in such a way that the patient table which is arranged approximately on the plane of the axis of rotation remains accessible from one side at all moments for the person treating the patient.
