Image reconstruction using filtered backprojection and iterative method: effect on motion artifacts in myocardial perfusion SPECT.

Unlabelled: Patient motion during myocardial perfusion SPECT is a common source of errors. The extent and severity of motion artifacts have been described for filtered backprojection (FBP) reconstruction. In recent years, iterative reconstruction has been used increasingly in reconstruction of myocardial perfusion SPECT images and has been shown to be more accurate than FBP even in cases of incomplete datasets.
