摘要:
A device for detecting an orientation and spacing of an X-ray source relative to an X-ray receiver comprises a projector which is disposed at a predetermined orientation and a predetermined spacing relative to the X-ray source, and is configured to project a predetermined pattern of electromagnetic waves in a direction of the X-ray receiver. A detector is configured to detect the predetermined pattern projected by the projector. A positioning detection device, connected to the detector and configured to receive an output signal from the detector, generates a positioning signal as a function the output signal. The positioning signal comprises information about the orientation and spacing of the X-ray source relative to the X-ray receiver.
