ABSTRACT:
A medical apparatus has an apparatus part which is motor-adjustable relative to a surface in a direction of at least one degree of freedom. A sensing card means comprising a plurality of sensing cards forms a matrix-like grid which is attachable to the surface in a range of adjustment of the apparatus part. The sensing cards each output a signal given the presence of a subject in the region of the respective sensing card. The signals output by these sensing cards are evaluated in dependence upon the desired adjustment direction in such a way that only the sensing card or cards of the matrix-like grid lying in the desired adjustment direction is or are taken into consideration. An adjustment of the apparatus part in the desired adjustment direction is suppressed when at least one sensing card taken into consideration outputs a signal indicating the presence of a subject.
