摘要： A ray beam guiding apparatus comprises a fan shaped ray beam guiding box 1, first and second collimators 8, 10, an engaging plate 4 to attach the narrower end of the guiding box 1 7 to a ray generator, and an extension plate 3b attached to the wider end of the guide box 1 on which is provided a beam detector support 11. The first collimator 8 is mounted to the guide box 1 and has sliding stoppers to adjust the profile of the ray beam in a first direction and a second direction perpendicular to the first direction. The second collimator 10 is mounted to the guide box 1 and has a calibration slit 10a. An adjusting member 5 connects the engaging plate 4 and the ray generator 7 and is used to adjust the distance between the guide box 1 and the beam generator 7. The guide box 1 may be used in a ray inspection system which performs X-ray security inspection of liquid articles such as a bottle containing liquid (the guide box has a circular aperture 14 through which articles to be inspected pass). The guiding box 1 adjusts both the size/shape of the ray beam and the centering of the ray beam, so that inspection quality can be improved and thickness of a ray shielding layer 12 can be reduced.
