Abstract
A positron emission tomography (PET) image attenuation correction method may be provided. The PET image attenuation correction method may include obtaining n three-dimensional (3D) magnetic resonance (MR) images and n 3D PET images classified based on a breathing state of an examined patient, generating attenuation correction maps with respect to the n 3D MR images using a single computed tomography (CT) image, obtained in advance, associated with the patient, correcting attenuation of the n 3D PET images based on the generated attenuation correction maps, and generating a single PET image by combining the n attenuation-corrected 3D PET images.
