Abstract

A nuclear-medical image is generated from a nuclear-medical data set that can be acquired with a dual modality tomography apparatus, which has both a scanner for acquisition of magnetic resonance images and a scanner for acquisition of nuclear-medical data sets within a common acquisition volume. A nuclear-medical data set and an MR image are thereby acquired, and a nuclear-medical magnetic resonance atlas is provided with a reference MR data set of the region of a reference patient to be imaged and a corresponding correction data set. A transformation that maps the reference MR data set to the MR image is generated and applied to the correction data set to generate a transformed correction data set that is registered with the nuclear-medical data set. The corrected nuclear-medical image is subsequently calculated from the transformed correction data set and the nuclear-medical data set.
