Systems and methods for image quality enhancement for out of focus regions for multi-head camera

Abstract:

A nuclear medicine (NM) multi-head imaging system is provided that includes a gantry, plural detector units mounted to the gantry, and at least one processor. Each detector unit defines a detector unit position and corresponding view oriented toward a center of the bore, and is configured to acquire imaging information over a sweep range. The at least one processor is operably coupled to at least one of the detector units, and is configured to acquire, via the detector units, imaging information. The imaging information includes focused imaging information corresponding to a focused region and background imaging information corresponding to surrounding tissue of the focused region. The at least one processor is also configured to reconstruct an image using the focused imaging information and the background imaging information using a first reconstruction technique for the focused imaging information and a different, second reconstruction technique for the background imaging information.
