Claim 0:
1. A system for image correction in positron emission tomography (PET), comprising:
at least one storage device including a set of instructions; and
at least one processor configured to communicate with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including:
acquiring a PET image and a computed tomography (CT) image of a subject;
generating a concatenated image based on the PET image and the CT image; and
generating, based on the concatenated image, an attenuation-corrected PET image of the subject by application of an attenuation correction model, wherein the attenuation correction model is a trained machine learning model.
