摘要：
Disclosed is a computer-implemented medical data processing method for determining a dose distribution for use in a medical procedure involving irradiation of an anatomical structure of a patients body with ionising radiation, the method comprising executing, on at least one processor of at least one computer, steps of: a) acquiring (S1), at the at least one processor, medical image data describing a medical image of the anatomical structure, wherein the anatomical structure comprises both a target region which defines a target of the irradiation and non- target tissue, wherein irradiation of the non-target tissue shall be avoided b) acquiring (S2), at the at least one processor, dose distribution data describing an irradiation dose distribution spatially defined in the reference system of the medical image of the anatomical structure c) determining (S3), by the at least one processor and based on the medical image data and the dose distribution data, prioritization data describing, for each image unit of the medical image describing non-target tissue, a priority of that image unit for consideration during an optimization of the irradiation dose distribution described by the dose distribution data d) determining (S4), by the at least one processor and based on the dose distribution data and the prioritization data, changed dose distribution data describing a changed irradiation dose distribution spatially defined in the reference system of the medical image of the anatomical structure, wherein the changed irradiation dose distribution is comprised in the output of at least a step of an optimization algorithm having the dose distribution data and the prioritization data as an input.La présente invention concerne un procédé de traitement de données médicales mis en œuvre par ordinateur pour déterminer une distribution de dose pour utilisation dans une procédure médicale mettant en œuvre lirradiation dune structure anatomique du corps dun patient avec un rayonnement io
