Medical apparatus having an adjustable apparatus part for application to the body surface of a patient

摘要

A medical apparatus has an apparatus part which is provided for application against the body surface of a patient, and a patient support mechanism and a system for adjusting the apparatus part and the patient support mechanism relative to each other. The system simultaneously adjusts the apparatus part at a first adjustment speed in a first direction and the patient support mechanism at a second adjustment speed in a second direction, with the first and second adjustment speeds having a fixed constant relationship, so that the apparatus part and the patient support mechanism are caused to execute a motion in a third direction relative to each other. The third direction can be selected to compensate for dislocations of the body of the patient which are anticipated upon the application of the apparatus part to the patient's body surface, so that the patient remains as stationary as possible.
