Abstract
Improvements are made in the movements of a gamma camera, especially a gamma camera provided with two detector heads, by supporting each of these detector heads with a stirrup provided with two flanks. A bearing can slide within each of the flanks. This bearing holds a pin for the angulation and holding of the detector head. Each detector head can thus be shifted in translation independently, when the two bearings shift together and in the same direction in the flanks. It can furthermore accept a movement of angulation when it is rotated on itself, even about these axes. It is shown that this device improves the ergonomy of use and that it furthermore enables better-quality imaging.
