ABSTRACT:
A combination of double and triple cell ganging which resolves any incompatibility between the number of detector channels and the lower number of DAS channels without requiring any significant hardware and software changes is described. In one specific embodiment, at least some detector cells on one side of the detector outside the FOV are wired in pairs, i.e., ganged, to form a set of 2 mm channels, and on the other side of the detector outside the FOV, at least some detector cells are wired together, i.e., ganged, to form a set of 3 mm channels. Such ganging of detector cells avoids having to make any significant hardware and software changes to known multislice CT systems.
