CONE BEAM SPOTLIGHT IMAGING USING MULTI-RESOLUTION AREA DETECTOR

A multi-resolution array detector includes a fine resolution zone having a higher density of detector elements than in a coarse resolution zone having a relatively lower density of detector elements. The array detector, usually an area detector, is used in computerized tomography (CT) imaging to provide a finer resolution image in one zone than in another zone. A method of processing data from the multi-resolution detector uses a non-uniform distribution of data in Radon space.
