    • A system for radiation therapy includes a radiation planning system. The radiation planning system includes a data processor that is adapted to receive information concerning an intended radiation treatment region of a body, receive a calculated initial energy released per unit mass for a plurality of locations within the body, compute a radiation dose at a plurality of locations within the radiation treatment region based on the calculated initial energy released per unit mass and including radiation dose contributions due to scattering from other locations within the body, and determine radiation therapy parameters for providing radiation treatment to the intended radiation treatment region based on the radiation dose computed at the plurality of locations within the radiation treatment region. Including radiation dose contributions due to scattering from other locations within the body take into account density discontinuities in the body.

    • It is an objective of the present invention to provide a system and a method for improving the quality of beam delivery in a system for proton therapy by pencil beam scanning of a predeterminable volume within a patient that minimizes the extent of possible beam position errors to an extent medically acceptable.
      This objective is achieved according to the present invention by a system and a method for the delivery of proton therapy by pencil beam scanning of a predetermined volume within a patient, comprising:
      a) a proton source in order to generate a proton beam being adjustable with respect to the beam intensity and/or beam energy, i.e. by means of a degrader;
      b) a number of proton beam bending and/or focusing units;
      c) a beam nozzle having an outlet for the proton beam to penetrate the predetermined volume of the patient;
      d) a beam bending magnet being disposed upstream of the nozzle;
      e) a couple of sweeper magnets in order to sweep the proton beam in both lateral directions;
      f) a position-sensitive detector being aligned with the nozzle in order to control the position of the proton beam; and
      g) a control logic for controlling the position and the energy of the proton beam comprising a beam steering data set;
      h) a correction logic aligned with the control logic for correcting beam position errors by comparing an expected beam position with the actual beam position detected in the position-sensitive detector and generating beam position correction data in dependency of the comparison results.
