BackgroundMotion artifacts are disruption in medical images caused by motion of the object being imaged. The elimination of motion artifacts is important when using multi-modality imaging systems; for example, Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT), a.....
