Abstract
Anti-scatter plates are used to attenuate secondary radiation so that it is not detected by a detector array. However, anti-scatter plates often cast dynamic shadows on the detector array which results in noise in signals produced by the detector array. As disclosed herein, an anti-scatter grid comprises at least two anti-scatter plates. A percentage difference in the shadows cast by the first and the second anti-scatter plates is substantially zero (e.g., causing uniform percentage change in shadows cast on the detector array). Additionally, the shadows that are cast by the anti-scatter plates may be substantially static. In one embodiment, this is accomplished by having a top surface of an anti-scatter plate that has a transverse dimension that is less than a bottom surface of the anti-scatter plate.
