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.
