The invention relates to an apparatus and a method for irradiating tumor tissue (3) of a patient (10) by means of an ion beam (2). For that purpose, the apparatus has a deflecting device (1) for the ion beam (2) for slice-wise and area-wise scanning of the tumor tissue (3) and an ion beam energy con
The invention relates to an apparatus and a method for irradiating tumor tissue (3) of a patient (10) by means of an ion beam (2). For that purpose, the apparatus has a deflecting device (1) for the ion beam (2) for slice-wise and area-wise scanning of the tumor tissue (3) and an ion beam energy control device for slice-wise and depth-wise scanning of the ion beam (2). An electromechanically driven ion-braking device (11, 12) is provided as a depth-wise scanning adaptation apparatus (5) for adapting the range of the ion beam (2) 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 (7) for detecting a temporal and positional change in the location of the tumor tissue (3) in a treatment space (8). A control device controls the deflecting device (1) and the depth-wise adaptation apparatus (5) for adjusting the ion beam direction and ion beam range, respectively, when scanning the tumor tissue (3) in the course of temporal and positional change in the location of the tumor tissue (3) in the treatment space (8).
