Abstract：The γ-ray AC (Attenuation Correction) was adopted for MR (Magnetic Resonance) images in
PET/MR (Positron Emission Tomography/Magnetic Resonance). In this paper, basic principles of PET
AC were expounded. Moreover, four PET/MR AC approaches and their application in brain or the whole
body were also introduced, including tissue classification, map registration, transmission scanning and
emission data reconstruction.
