SYSTEM AND METHOD FOR PARTIAL SCAN ARTIFACT REDUCTION IN MYOCARDIAL CT PERFUSION |
摘要 |
A system and method is provided for reducing partial scan reconstruction artifacts in sinogram data acquired as a series of sets of partial-scan projection views, each set of projection views extending over an angular range of less than 360 degrees. A full-scan sinogram matrix for each of the sets of projection views in the series is created and each set of partial-scan projection views is stored in a respective full-scan sinogram matrix to create an array of full-scan matrices having respective empty spaces not filled by partial-scan projection view data stored therein. The empty spaces are filled in each of the full-scan sinogram matrices using the partial-scan projection view data stored therein and an image of the subject is reconstructed from the full-scan sinogram matrices having the empty spaces filled using the partial-scan projection view data stored therein.
