A method for creating an attenuation correction for a combined positron emission tomography-magnetic resonance device

The invention relates to a method, a computer program product and a computer readable storage medium for creating a utilized for attenuation correction of positron emission tomography image data sets global attenuation map in a combined magnetic resonance, positron emission tomography device. In the identification of hardware components of the combined magnetic resonance, positron emission tomography device, and the determination of the positions of the detected hardware components relative to a patient support global attenuation map is generated in dependence on the detected hardware components.
