摘要
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 classiifcation, map registration, transmission scanning and emission data reconstruction.关键词
