Hybrid mr/pet with correction for radiation absorption by mr coil

An imaging system comprising:

• a magnetic resonance imager configured to acquire magnetic resonance data of a subject;
• a nuclear imager configured to acquire nuclear imaging data from the subject;
• a subject support configured to support the subject for acquisition of magnetic resonance data by the magnetic resonance imager and for acquisition of nuclear imaging data by the nuclear imager without repositioning the subject on the subject support;
• a magnetic resonance component disposed with the subject on the subject support at a determinable position respective to a frame of reference of the nuclear imager, the magnetic resonance component cooperating with the magnetic resonance imager in the acquisition of magnetic resonance data;
• and
• a nuclear image reconstruction processor configured to reconstruct the nuclear imaging data to generate a nuclear image of at least a portion of the subject, the nuclear image reconstruction processor including a data corrector that adjusts at least one of the nuclear imaging data and the nuclear image based on a density map of the magnetic resonance component to correct the nuclear image for radiation absorption by the magnetic resonance component.
