Patent Images
1. A device for producing a radiation treatment plan, the device comprising:
- a computer unit having an input device and an output device, the device being operable to;
specify a dataset in which an object, which is to be irradiated, is represented,determine a target volume requiring to be irradiated within the object,ascertain an index identifying a density heterogeneity for a region that will be struck by a planned treatment beam, anddetermine as a function of the ascertained index a safety margin for the target volume requiring to be irradiated.

Abstract
The present embodiments relate to producing a radiation treatment plan. In one embodiment, the method may include specifying a dataset in which an object requiring to be irradiated is represented; determining a target volume requiring to be irradiated within the object; ascertaining a metric identifying a density heterogeneity for a region that will be struck by the planned treatment beam; and determining as a function of the ascertained metric a safety margin for the target volume requiring to be irradiated.

7. A device for producing a radiation treatment plan, the device comprising a computer unit having an input device and an output device, the control unit being operable to:
-
specify a dataset in which an object, which is to be irradiated, is represented, determine a target volume that is to be irradiated within the object, specify at least two irradiation fields with which the target volume will be irradiated from in each case a different direction, ascertain for each irradiation field an index that identifies a density homogeneity for a region which will be struck during planned irradiating with the respective irradiating field, and determine a weighting for the at least two irradiating fields as a function of the index ascertained. - View Dependent Claims (8, 9, 10, 11, 12, 15)
