| 20100301235 | METHOD AND APPARATUS FOR IRRADIATION OF A MOVING TARGET VOLUME - 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. | 12-02-2010 |
| 20120161038 | ACCELERATOR AND METHOD FOR IRRADIATING A TARGET VOLUME - A device operable to accelerate a particle beam to an energy for irradiating a target volume. The device includes a particle accelerator operable in a first working phase in which particles of the particle beam are accelerated to the energy and a second working phase in which the particles of the particle beam are provided and extracted for irradiating the target volume. The device further includes a control device operable to interrupt an irradiation of the target volume if the target volume assumes a predetermined state. The control device is also operable to control the particle accelerator as a function of a comparison between a residual particle number stored in the accelerator and a reference value. | 06-28-2012 |
| 20120264996 | METHOD AND DEVICE FOR IRRADIATION TREATMENT PLANNING - A method for irradiation treatment planning for a target volume to be irradiated includes specifying a plurality of data sets. The target volume to be irradiated is depicted in each data set of the plurality of data sets. The data sets differ in that the target volume has another position and/or shape. A data set is selected from the plurality of the data sets and other data sets are registered to the selected data set. The method includes forming an amalgamation of the depicted target volumes using the registrations of the other data sets to the selected data set, and determining an area at risk in the selected data set. The method includes modifying the amalgamation of the target volumes such that the area at risk is excluded from the amalgamation of the depicted target volumes. An irradiation treatment plan is calculated using the modified amalgamation of the target volumes. | 10-18-2012 |
| 20130150647 | Irradiation Planning for Particle Therapy - A method for producing an irradiation plan for a target volume includes preparing a modulation curve that characterizes modulation of particle numbers at target points in the target volume that lie one behind another in a direction of the beam. The method also includes determining a current position of the target volume and defining a plurality of target points that fully cover the target volume in the current position. Particle numbers are assigned to the plurality of current target points using the modulation curve. | 06-13-2013 |
| 20130177135 | Method for Determining a 4D Plan for Carrying out Intensity-Modulated Radiation Therapy - A method for determining a 4D plan for carrying out intensity-modulated radiation therapy of a target volume subject to irregular periodic motion, with a radiation therapy apparatus is provided. The method includes selecting positions of a radiation source. The number of positions is selected to be identical in all 3D radiation therapy plans. The method also includes selecting a number of respective aperture settings assigned to a respective position of the radiation source to be identical in all 3D radiation therapy plans. A geometrical, temporal, and/or dynamic restriction that restricts a change of the aperture from one aperture setting to another aperture setting is predetermined, and the 3D radiation therapy plans are determined such that the 3D radiation therapy plans fulfill predetermined restrictions for aperture settings in each case. | 07-11-2013 |
