MODEL-BASED EXTENSION OF FIELD-OF-VIEW IN NUCLEAR IMAGING |
摘要 |
<p>A CT imaging system (12) generates structural data of a first FOV which is reconstructed by a CT reconstruction processor (52) into a CT image representation. A nuclear imaging system acquires functional data from a second FOV which is smaller than the first FOV. A first PET reconstruction processor (60) reconstructs the functional data into a PET image representation. A fusion processor (64) combines the PET image representation with a map extracted from the CT image representation to generate an extended FOV image representation. A spill-over correction unit (66) and a backscatter correction unit (68) derive spill-over correction data and backscatter correction data from the extended FOV image representation. A reconstruction processor (70) generates a spill-over and backscatter corrected functional image representation based on the spill-over correction data, the backscatter correction data, and the functional data.</p> |
