摘要： Abstract: A control parameter is determined for a system (10) for irradiating a predetermined target volume in a body (77) with a particle beam (75). The system is constructed to direct the particle beam at a multiplicity of target points (30) in the target volume in succession in order to produce at, each of the target points a predetermined dose distribution (42) in a region around the target point. The control parameter controls the extent of an overlap of the dose distribution of a first target point with the dose distributions of neighbouring target points. For determination of the control parameter, there is first determined (94) a movement parameter which quantitatively characterises the movement of the body at the first target point. The control parameter is determined (95) in dependence on the movement parameter.

摘要： A system for irradiating a predetermined target volume in a body with a particle beam is constructed to direct the particle beam at a multiplicity of target points in the body in succession, in order to produce at each of the target points a predetermined dose distribution. For the system there is determined a planning target volume by first determining, in a fictive homogeneous body, a target volume equivalent to the minimum target volume in the body. The equivalent target volume is extended by a safety margin, in order to determine the planning target volume.

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.
