摘要:
Systems and methods for compensating motion artifacts in positron emission tomography (“PET”) imaging based on medical images acquired with a medical imaging system are provided. In some embodiments, the method includes acquiring PET data from a subject with a PET system during which at least a portion of the subject is undergoing motion, and providing medical images acquired from the subject using a medical imaging system, the medical images including regions depicting motion. The method also includes estimating, from the medical images, motion information associated with the motion of the at least a portion of the subject, and reconstructing a motion-corrected PET image using the PET data using a reconstruction algorithm that incorporates the motion information into a system matrix.
