Abstract
For larger FOV in a gamma camera, multiple solid-state detectors are tiled. The edge pixels of the pixelated detectors are smaller than interior pixels so that the pitch of the pixels or anodes is constant across the tiled detectors. The constant pitch occurs where pairs of edge pixels combined from different detectors contribute the pitch or area of an interior pixel. As a result of this optimized edge pixel pairing and corresponding regular pitch across the tiles, the spectral and other performance is less degraded.
Claims10
A detector system comprising:
- a first detector having a plurality of first pixelated detector cells including first interior detector cells and first edge detector cells on a first edge of the first detector;
- and
- a second detector having a plurality of second pixelated detector cells including second interior detector cells and second edge detector cells on a second edge of the second detector;
- wherein the first detector is tiled with the second detector such that the second detector is positioned adjacent to the first detector where the first edge is by the second edge;
- wherein the first edge detector cells have a first lesser area than the first interior detector cells, the second edge detector cells have a second lesser area than the second interior detector cells;
- and
- wherein the first and second lesser areas are sized such that a pair of an abutting first edge detector cell and an abutting second edge detector cell combine to form a combination cell having substantially the same area and shape as one of the first interior detector cells so that a pitch of the first and second pixelated detectors cells across the first and second detectors is constant.
