Embodiment Construction

[0031] Specific embodiments of the present invention are described by the following figures.

[0032] FIG. 1 shows a block diagram of an embodiment of the present invention, that is, a view showing a combination of a schematic diagram showing a mechanical configuration and a block diagram of a system configuration.

[0033] The X-ray detector 2 is arranged horizontally opposite to the X-ray source 1 , and a sample stage 3 for placing a see-through object W is inserted between them. The sample stage 3 includes a moving device, which can move from the X-ray optical axis direction of the X-ray source 1 (in the X-axis direction), on the Y-axis direction perpendicular to the X-axis direction on the horizontal plane, and in the vertical direction. Move in the direction of the Z axis. Further, the sample stage also includes a rotating device that rotates (Φ) around a rotating central axis R parallel to the Z axis, and also includes a tilting device that tilts (θ) around a tilting ce...

Abstract

A fluoroscope capable of recognizing the examining direction or position of a fluoroscopic object intuitively and easily at all times without requiring a work for confirming the examining position or direction by reducing the fluoroscopic magnification. An optical camera (5) for photographing a fluoroscopic object W on a sample stage (3) is provided, the fluoroscopic object W is photographed by the optical camera (5) in a plurality of postures by driving the sample stage (3) prior to fluoroscopic work and the optical images are stored in a storage device (14). During fluoroscopic operation, an optical image O closest to the image of the fluoroscopic object W viewed from the examining direction at the current moment in time is selected from among the optical images stored in the storage device (14) and displayed on a display (13) so that the examining direction can be recognized intuitively. The examining direction can also be recognized intuitively when a marker M indicative of the position of the optical axis L of X-rays is displayed superimposingly in addition to the optical image O.

Description

technical field [0001] The present application relates to an industrial X-ray fluoroscopy device, and more particularly, relates to an X-ray fluoroscopy device suitable for non-destructively observing internal damage of objects such as aluminum castings and the like. Background technique [0002] The X-ray fluoroscopy device that fixes the sample stage of the object to be inspected (see-through object) is inserted between the X-ray source and the X-ray detector and moves and rotates is a device known so far for non-destructive detection of internal damage such as aluminum castings (such as See Patent Document 1). [0003] In this type of device, since the position and attitude of the fluoroscopic object depend on the position and rotation angle of the sample stage, the operator usually observes the X-ray fluoroscopic image through the window on the cover of the device or checks the Seeing through the position and attitude of the object and simultaneously operating the drive...
