Abstract:
Apparatus for producing multiple image slice data responsive to incident radiation passing through an object, comprising;a detector array comprising a plurality of parallel rows of detector elements, which receive said incident radiation and generates signals in response thereto, each of said rows being characterized by a row length and a detector width, measured in a direction perpendicular to the row length;said detector width being measured without collimation;signal processing circuitry which receives signals from said detector elements and which selectively combines the signals from one or more adjacent rows in one of a plurality of combination modes to form a plurality of group signals, said group signals representing the width of a slice, said slice width being different for each of said combination modes; andwherein the rows in the detector array having at least three substantially different detector widths.
