  • Method for preparing an irradiation plan for a moving target volume without a movement compensation
    Patent number: 9694203
    Abstract: A method for preparing a radiation treatment plan for irradiating a target volume region moving in regions in an object with a moving particle beam includes determining, using a mapping function dependent on a movement state (k) of the moving target volume region, a dose input in at least one target point volume (Vj). The dose input is brought about by applying the particle beam to an irradiation point (Bi).
