X-ray examination apparatus having an automatic positioning system for an imaging system

摘要

A versatile X-ray examination apparatus including a movable table top for supporting a patient, an imaging system having an X-ray source adopted for passing X-rays through the patient and an image receptor for generating an X-ray image of the patient, the image receptor is automatically moved to a desired position by a control system. The control system includes a memory for storing data concerning the table top, a control circuit for detecting a plurality of moving amounts of a plurality support members for supporting the imaging system, and a moving amount calculator for calculating a moving amount of the image receptor along a radiation axis on the basis of the data in the memory and the detected moving amount data provided from the control circuit.
