摘要：A gamma camera has a plurality of exchangeable collimators, one of which isreplaceably mounted in the ray inlet opening of the camera, while the others are placedon separate supports. The invention is particularly characterized in that the supports areswingably mounted upon a column one above the other.

In the illustrated embodiment, the camera is swingable through about 90° to acollimator exchange position, and each of the separate supports is swingable to avertically aligned position, with resilient limiting of the swinging movement and resilientpositioning of the support at the desired exchange position. Further, the collimators arecarried on the supports by means of a series of vertically disposed coil springs,projections on the camera being relatively movable from above into grooves of thecollimator at the exchange position, whereupon the collimator is so turned that it issecurely prevented from falling out of the camera head.
