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.

A monitoring and control arrangement which includes a plurality of control desks each having control, measuring and monitoring elements. The arrangement is assembled of a suitable number of control desks which, on the one hand, permits the precise positioning of the control desks in an extended configuration along a wall and, on the other hand, in an arcuate form pursuant to ergonomic viewpoints.

Monitoring and control arrangement

A collimator for a ray diagnosing device for taking pictures produced by gamma rays or similar penetrating rays consists of a honeycomblike constructed body with many holes, the walls of which absorb the rays. The invention is particularly characterized in that the walls of the collimator are made of strips which extend parallel to each other in their longitudinal directions and are so folded transversely to their longitudinal extension that when two strips are placed next to each other one side of a strip makes a series of holes with the adjacent side of the following strip, the holes having a symmetry axis which coincides with the line separating the two strips.

Collimator for a ray diagnosing device

A device for supporting a patient, having a carrying member and a horizontally extending lying support for the patient, with a motor for varying the distance between the support and a medicinal unit. The invention is particularly characterized by the provision of a spring scale between the patient support and its carrying member, having a switching member which can be shifted corresponding to the weight of the patient. Switching means are connected with the switching member for interrupting the current circuit of the motor, the distance between the switching means and the switching member being adjustable.
