    摘要: 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).

    摘要: The invention relates to an ion beam scanning system having an ion source device, an ion acceleration system and an ion beam guidance system comprising an ion beam outlet window for a converging centered ion beam, and a mechanical alignment system for the target volume to be scanned. For that purpose, the ion acceleration system can be set to an acceleration of the ions required to obtain a maximum depth of penetration. The scanning system also has energy absorption means arranged in the path of the ion beam between the target volume and the ion beam outlet window transverse to the center of the ion beam. The energy absorption means can be displaced transverse to the center of the ion beam in order to vary the energy of the ion beam, so enabling, in the target volume, depth modulation of the ion beam, which is effected by means of a linear motor and the transverse displacement of the energy absorption means, with depth-staggered scanning of volume elements of the target volume in rapid succession. The invention relates also to a method of ion beam scanning and a method of operating an ion beam scanning system using a gantry system.

    摘要: A method of determining an actual, especially an actual effective, radiation dose distribution of a moving target volume includes detecting first and further positions of volume elements of the target volume in a first and at least one further motional state of the moving target volume, determining transformation parameters by transformation of the first positions into the further positions, irradiating the moving target volume in accordance with an irradiation plan which comprises a plurality of raster points to be irradiated, wherein during the irradiation of a raster point it is detected which of the motional states is occupied by the moving target volume, assigning raster points to subirradiation plans and determining the actual effective dose for each of the plurality of volume elements, in each case from contributions from the raster points of the subirradiation plans using the transformation parameters. Calculation and application of correction parameters which compensate for changes, caused by movement, to the position of the Bragg maximum and to the biologically effective dose applied.
