Abstract
The invention relates to an apparatus and a method for irradiating tumor tissue ( ) of a patient ( ) by means of an ion beam ( ). For that purpose, the apparatus has a deflecting device ( ) for the ion beam ( ) for slice-wise and area-wise scanning of the tumor tissue ( ) and an ion beam energy control device for slice-wise and depth-wise scanning of the ion beam ( ). An electromechanically driven ion-braking device ( ) is provided as a depth-wise scanning adaptation apparatus ( ) for adapting the range of the ion beam ( ) and has faster depth-wise adaptation than the energy control device of an accelerator. The movement of a patient is monitored by means of a movement detection device ( ) for detecting a temporal and positional change in the location of the tumor tissue ( ) in a treatment space ( ). A control device controls the deflecting device ( ) and the depth-wise adaptation apparatus ( ) for adjusting the ion beam direction and ion beam range, respectively, when scanning the tumor tissue ( ) in the course of temporal and positional change in the location of the tumor tissue ( ) in the treatment space ( ).
