Method for absorption correction of PET data and MR-PET system

摘要

The invention relates to a device for combined magnetic resonance tomography and positron emission tomography imaging, which is designed to receive PET image data of an examination person (104) from an examination area (107), characterized in that the device (100) further comprising: - an additional scanning unit (103) configured to scan a predetermined area of the subject (104) and to determine, based on the scan, an outline of the subject for the predetermined area, and - a computer unit (111), configured to perform absorption correction of PET data taken from the predetermined area of the subject (104) based on the determined contour.
