Abstract
A method is disclosed for producing an attenuation map for a component of an MR/PET system. In at least one embodiment, the method includes ascertaining attenuation values of the component, producing a basic map from the attenuation values, ascertaining a position of the component relative to an examination volume of the MR/PET system, and producing the attenuation map by correcting the basic map using the ascertained position. This enables the actual position of the components to be taken into account in the attenuation correction.
