Abstract
A device for moving an X-ray apparatus embodied in the form of a C-bow ( ) in a controlled manner, the C-bow ( ) being mounted on a pedestal ( ) provided with motor-driven rollers ( ) controllable in their direction of travel in such a way that it is displaceable in parallel in relation to at least two axes ( ) and rotatable relative to three axes ( ), each movement of the C-bow ( ) with respect to a coordinate system ( ) which is stationary relative to the room being carried out via controllable drive devices ( ). These drive devices ( ) are controlled either by means of a control device ( ) or via a computer ( ), said control device being operated either via a sterile control console or by voice control. Any positions and projections of the C-bow ( ) that have once been adjusted may be stored in the computer ( ), so that a desired position and projection may be reproduced again. If the C-bow is combined with a surgical navigation system which comprises a position detector ( ), it is possible, by measuring a reference base that is applied to a patient ( ) and is provided with optical markers ( ), to consider changes in the position of the patient ( ) in such a way that an adjusted position and projection of the C-bow ( ) can be reproduced after the patient ( ) has changed position.
