Abstract
The present invention, in one form, is an imaging system for generating images of an entire heart. In one embodiment, projection data is collected for a field of view containing only the heart so that the total detector size is reduced. The smaller detector allows the use of a plurality of source-detector pairs so that projection data for an angular coverage of (&pgr;+fan angle) is collected by rotating a gantry significantly less than one complete rotation. Therefore, projection data is collected in significantly less than one cardiac cycle, minimizing motion artifacts.
