Patent number: 10252082Abstract: A method is disclosed for irradiation planning for the irradiation of a moving target volume located in a body with a particle beam irradiation facility by means of rescanning, which method has the steps of defining the target volume in a reference condition of the motion, dividing the target volume among a plurality of target points that can be individually approached with a particle beam, calculating a nominal dose to be deposited in each of the target points of the target volume, defining a number of rescanning passes in which each of the target points of the target volume are approached, calculating a mean motion to be expected of the target points of the target volume based on a motion model, taking into account the mean motion to be expected of the target points of the target volume in the irradiation planning in such a manner that the deviation of the expected dose deposition from the nominal dose for each target point is determined, and the nominal dose for each target point is corrected on the basisType: GrantFiled: October 18, 2013Date of Patent: April 9, 2019Assignee: GSI Helmholtzzentrum für Schwerionenforschung GmbHInventors: Christoph Bert, Alexander Gemmel, Dirk Müssig, Robert Lüchtenborg

Patent number: 9861835Abstract: A method for determining a dose of radiation input into an object irradiated with an energetic particle beam includes determining, during the application of the radiation, a dose input into at least one volume region of the object. The at least one volume region of the object lies outside a target volume region. The dose input into the at least one volume region is determined with a calculation that is based at least in part on a physical model of the energetic particle beam.Type: GrantFiled: December 3, 2012Date of Patent: January 9, 2018Assignee: GSI HELMHOLTZZENTRUM FUER SCHWERIONENFORSCHUNG GMBHInventors: Christoph Bert, Robert Luechtenborg

Patent number: 9119962Abstract: A method for controlling dosage application during irradiation of a moveable target volume in a body with an energy beam by scanning the target volume includes, before irradiating an i-th grid position, determining a dosage during the irradiation process using the movement data, wherein the dosage already contains the i-th grid position during irradiation of the previous grid positions (1<=k<i). Depending on the determined dosage that already contains the i-th grid position during the irradiation of the previous grid positions (1<=k<i), a compensation value for the i-th grid position is calculated, and depending on the compensation value and on the nominal particle fluence for the i-th grid position, a compensated particle fluence (Fikomp) is calculated for the i-th grid position in order to irradiate the i-th grid position with the compensated particle fluence (Fikomp).Type: GrantFiled: August 31, 2010Date of Patent: September 1, 2015Assignee: GSI HELMHOLTZZENTRUM FUER SCHWERIONENFORSCHUNG GMBHInventors: Christoph Bert, Robert Luechtenborg

Patent number: 9018593Abstract: A method actuates a device for irradiating an object that has at least one target volume to be irradiated and at least one volume to be protected. The method includes defining at least one signal dose value for the volume to be protected and irradiating the object at least one of at least at times and at least in part with hadron irradiation. A dose introduced into the volume to be protected during the irradiation of the object is determined and at least one signal is emitted as soon as the introduced dose exceeds at least one signal dose value in at least one point of the volume to be protected.Type: GrantFiled: December 2, 2010Date of Patent: April 28, 2015Assignee: GSI Helmholtzzentrum fuer Schwerionenforschung GmbHInventors: Robert Luechtenborg, Christoph Bert, Daniel Richter
