ABSTRACT:
In the case of a patient support apparatus, a support, rotatably mounted about a horizontal spatial axis, is height-, longitudinally- and laterally-adjustable relative to an x-ray apparatus, whereby at least the height adjustment proceeds by a motor. In order, in the case of a lengthwise displacement of the patient support, to automatically conduct such a height adjustment that the isocenter moves along a path--capable of being established in advance--along the support, it is provided in accordance with the disclosure that a processor constantly determines, for the actual coordinates of the spatial axis and of the tilt angle .alpha. of the support, the height of a desired examination point and compares it with the height of the isocenter. A follow-up control coupled with the processor ensures a constant adaptation of these two values.
