Medical apparatus having an apparatus part which is motor-adjustable relative to a surface in a direction of at least one degree of freedom
First Claim
1. A medical apparatus, comprising:
- an apparatus part and means for motor-adjustable positioning of the apparatus part relative to a surface in a direction of at least one degree of freedom;
control means for controlling the adjustment of the apparatus part, said control means having a sensing card means connected thereto comprising a plurality of sensing cards forming a matrix-like grid and attached to the surface in a range of adjustment of the apparatus part, said sensing card means outputting a respective signal associated with at least one of the sensing cards given presence of an object in a region of the respective ones of said sensing cards; and
said control means evaluating said respective signal outputted by the sensing cards in dependence on a desired adjustment direction of the apparatus part such that it only takes into consideration the signals of those sensing cards of the matrix-like grid which are immediately proximate to the apparatus part in said desired adjustment direction, and suppresses an adjustment of the apparatus part in the desired adjustment direction when at least one sensing card taken into consideration outputs a signal indicating the presence of the object.

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.

8. A medical system, comprising:
-
a patient table and means for motor-adjustable positioning of the patient table relative to a surface in a direction of at least one degree of freedom; control means for controlling the adjustment of the patient table, said control means being connected to a sensing card means comprising a plurality of sensing cards forming a matrix-like grid and attached to the surface in an adjustment region of the patient table, said sensing card means outputting a respective signal associated with each sensing card which detects the presence of an object in a region thereof; and said control means evaluating said respective signals outputted by the sensing card means based on a desired adjustment direction of the patient table such that it only takes into consideration the respective signals of those sensing cards of the matrix-like grid which are predetermined to be a hazard for said desired adjustment direction if the object is in the region thereof and suppresses an adjustment of the patient table in the desired adjustment direction when at least one sensing card taken into consideration inputs a signal indicating the presence of the object. - View Dependent Claims (9)
