Abstract: Disclosed is a method for determining a deviation of the position of an anatomical body part relative to a predetermined position defined by a radiation treatment plan. A monitoring image is taken of the anatomical body part at the instant that a predetermined control point defined in the treatment plan has been reached. The monitoring image is compared to a simulated image simulated from a planning image of the anatomical body from the perspective of a monitoring camera used to generate the monitoring image. The comparison allows for a determination of whether there is a positional deviation.

Abstract: A method for determining dosage when planning radiotherapy and/or radiosurgery procedures can include imaging an irradiation target area using an imaging method, which can differentiate functional and/or biologically active regions of the irradiation target area. Ascertained activity values can be allocated to individual regions of the imaged irradiation target and irradiation doses can be assigned to the regions in accordance with the activity values. A nominal dosage distribution, which can be ascertained from the irradiation dosages for the regions, can be used as an input value for treatment planning.

Abstract: A method for positioning a patient or detecting a target volume in radiotherapy or radiosurgery includes positionally referencing at least one implant in the vicinity of the target volume and inductively stimulating the at least one implant. Emission from the at least one inductively stimulated implant is detected and a position of the at least one implant is determined based on the detected emission. The current position of the target volume is determined based on the determined position of the at least one implant. Further diagnostic, two-dimensional or three-dimensional image data sets can be recorded in accordance with breathing.
