摘要：
Provided are an apparatus and method for improving image resolution in a positron emission tomography (PET), which may reconstruct a high-resolution image in a PET system using a motion of an entire detector or a bed motion and may maintain a characteristic of a sinograms using a positive number in a sinogram computing, by applying a super-resolution algorithm that may be based on a maximum likelihood expectation maximization (MLEM) algorithm.
