CT SCANNER WITH SEGMENTED DETECTOR ARRAY

A plurality of segmented radiation sensitive arrays (30) receive radiation from a radiation source (16) which has transversed an examination region (14) of a CT scanner (10). Each array includes a plurality of rows (A, B, C) of radiation sensitive cells, e.g. photodiodes, which produce an electrical signal indicative of the intensity of radiation received. Within each of the rows, there are larger cells and smaller cells. The electrical signals from each of the plurality of cells within each row are serialized (34) and amplified (36A, 36B, 36C). Selected combinations of the electrical signals from the various rows and larger and smaller elements within each row are combined (46) and reconstructed (50) into an image representation (52) for display on a video monitor or the like.
