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.

Method for determining a dose entering an object that is to be irradiated

The present disclosure relates to a method and to an irradiation system for irradiating a moving target volume with an ion beam, in particular for tumor therapy, wherein ion radiography measurements of the target volume are performed and the irradiation for deposition purposes and for radiography purposes is performed with the same ion beam but consecutively in time by alternating the energy of the ion beam between a higher radiography energy and a lower deposition energy using, for example, a passive energy modulator proximal with respect to the patient.

Method and irradiation installation for irradiating a target volume

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&#x3c;=k&#x3c;i). Depending on the determined dosage that already contains the i-th grid position during the irradiation of the previous grid positions (1&#x3c;=k&#x3c;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 (F) is calculated for the i-th grid position in order to irradiate the i-th grid position with the compensated particle fluence (F).

Method and device for controlling dosage application during irradiation

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.
