Method for determining dosage when planning radiotherapy and/or radiosurgery procedures

摘要

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.
