IMPROVED POSITRON EMISSION TOMOGRAPHY CAMERA Abstract A positron emission tomography camera having a plurality of detector rings positioned side-by-side or offset by one-half of the detector cross section around a patient area to detect radiation therefrom. Each ring contains a plurality of scintillation de- tectors which are positioned around an inner circum- ference with a septum ring extending inwardly from the inner circumference along each outer edge of each ring. An additional septum ring is positioned in the middle of each ring of detectors and parallel to the other septa rings whereby the inward extent of all the septa rings may be reduced by one-half and the number of detectors required in each ring is reduced. Each detector ring or offset ring includes a plurality of photomultiplier tubes and a plurality of scintilla- tion crystals are positioned relative to the photo- multiplier tubes whereby each tube is responsive to more than one crystal. Each alternate crystal in the ring is offset by one-half or less of the thickness of the crystal such that the staggered crystals are seen by more than one photomultiplier tube. This sharing of crystals and photomultiplier tubes allows identification of the staggered crystal and the use of smaller detectors shared by larger photomultiplier tubes thereby requiring less photomultipler tubes, creating more scanning slices, providing better data sampling, and reducing the cost of the camera. The offset detector ring geometry combined with the additional septa reduces the cost of the positron camera and improves its performance.
