Abstract
Preassembled detector modules, each containing several detectors, and preassembled anti-scatter modules, each containing several anti-scatter plates, are mounted on a spine, which is attached to the rotating gantry of a CAT scanner by adjustable end supports. A pair of dowel pins in accurately drilled reference holes in the spine control the location and alignment of each module, one in a module round hole and one in a module slot. Critical dimensions in the modules are referenced to the hole, the slot, and reference surfaces on the modules contact the spine so as to reduce tolerance build-up. As such the modules can be easily manufactured using standard machine tools, and easily assembled and secured to a rotatable disk of a tomographic system.
