abstractsPET/MR is the most advanced molecular imaging device nowadays,The PET image needs to be quantified by attenuation correction(AC) to obtain the real activity distribution of radioactive drugs.The principle of AC of PET/MR and four methods of AC are briefly described in this paper.This paper mainly introduces the tissue segmentation and atlas method.A more promising launch data reconstruction method is also introduced in this paper.
