X-RAY FLUOROSCOPIC INSPECTION APPARATUS FOR DISPLAYING FLUOROSCOPIC IMAGE OF OBJECT TO BE FLUOROSCOPED ON MONITOR SCREEN OR RADIOGRAPHIC FLUOROSCOPIC IMAGE

摘要

PURPOSE: An X-ray fluoroscopic inspection apparatus for displaying a fluoroscopic image of an object to be fluoroscoped on a monitor screen or a radiographic fluoroscopic image is provided to maintain an original position of a viewpoint of a sample within a visual field of an X-ray camera and an original fluoroscopic magnification factor when the X-ray camera is tilted. CONSTITUTION: An X-ray camera(3) is installed at an incident position of an X-ray emitted from an X-ray source(1). A sample table(2) is installed between the X-ray source and the X-ray camera in order to support a sample. A tilting mechanism(31) is used for tilting the X-ray camera to a given tilting direction. A position moving mechanism(21,22) is used for moving the sample table to an x-axis and a y-axis orthogonal to each other. A rotating mechanism(23) is used for rotating the sample table together with the position moving mechanism. A position correction moving mechanism is used for moving the sample table together with the rotating mechanism and the position moving mechanism in the tilting direction of the X-ray camera. A z-axis moving mechanism(25) is used for moving the sample table together with the position correction moving mechanism, the rotating mechanism, and the position moving mechanism to the z-axis direction. A tilting tracing mechanism is used for driving the correction moving mechanism and the z-axis moving mechanism according to a tilting angle of the X-ray camera.
