| 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 |
