A medical system, such as an X-ray diagnostic device, having adjustable components, including a patient table, and having a monitoring device for determining the relative positions of the components and preventing collisions between them. Signals indicating the positions, the directions of motion and the speeds of movement of the components are fed directly from the drives and sensors of the components to the monitoring device. Calculations for controlling the components are carried out by a neural network, which has been appropriately trained in a learning phase.

An X-ray exposure apparatus has an X-ray exposure system that rotates during an image exposure wherein sharp images are generated despite the motion employs a digital filtering of the image information ensues taking the exposure time and the motion of the X-ray exposure system into consideration, thereby eliminating motion artifacts.

A circuit arrangement for accurately measuring the x-ray tube current substantially eliminates measurement errors by taking the displacement current caused by the capacitance of the high-voltage cable into account in the measurement. A test voltage is taken across a precision resistor. Another voltage is tapped at a location which includes the high-voltage cable capacitance and is supplied to a status monitor which differentiates this voltage and generates a voltage signal which is superimposed on the test voltage for forming a current signal which accurately represents the x-ray tube current.
