System for taking wide-field beam-eye-view (BEV) x-ray-images simultaneously to the proton therapy delivery
First Claim
1. A system for an intensity-modulated proton therapy of a predetermined target volume within an object, comprising:
- a proton source in order to generate a proton beam;
a number of proton beam forming units;
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;
a beam bending magnet being disposed upstream of the nozzle; and
an x-ray tube and an x-ray imager wherein the x-ray tube is associated with an irradiation channel within the beam bending magnet;
said irradiation channel being oriented along a prolongation of a nominal proton beam direction thereby delivering an x-ray beam along a proton beam direction.

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.

10. A method for delivering an intensity-modulated proton therapy to a predetermined target volume within an object, comprising the steps of:
-
providing a proton source in order to generate a proton beam; providing a number of proton beam forming units in order to form the proton beam in a predetermined manner; providing a beam nozzle having an outlet for the proton beam in order to penetrate the predetermined target volume of the object with the proton beam, providing a beam bending magnet being disposed upstream of the nozzle; and applying an x-ray beam along an irradiation channel within the beam bending magnet;
said irradiation channel being oriented along a prolongation of a nominal proton beam direction in order to deliver the x-ray beam along a proton beam direction to the target volume. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
