Abstract: A gamma camera has a plurality of exchangeable collimators, one of which is replaceably mounted in the ray inlet opening of the camera, while the others are placed on separate supports. The invention is particularly characterized in that the supports are swingably mounted upon a column one above the other.In the illustrated embodiment, the camera is swingable through about 90.degree. to a collimator exchange position, and each of the separate supports is swingable to a vertically aligned position, with resilient limiting of the swinging movement and resilient positioning of the support at the desired exchange position. Further, the collimators are carried 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 the collimator at the exchange position, whereupon the collimator is so turned that it is securely prevented from falling out of the camera head.
