Abstract

Apparatus for producing multiple image slice data responsive to incident radiation passing through an object. The apparatus includes a detector array having a plurality (p) of parallel rows of detector elements which receive such incident radiation and generate signals therefrom, each of which rows is characterized by a width measured prior to collimation in the direction perpendicular to a long dimension thereof; and signal processing circuitry which receives signals from the detector elements and which combines the signals in a first combination mode and in at least m additional combination modes. In the first combination mode, the circuitry forms a set of n groups of rows, each such group of rows having an effective group width substantially equal to the effective group width of each of the other groups in the set. In each of the m additional combination modes, the circuitry forms different sets of n groups of rows, each such set having a different effective group width common to all groups in the set.
