BEAMSTOP ARRAY AND METHOD THEREOF

摘要

The present invention relates to a beam-stop array. The beam-stop array includes: a first rectangular acrylic plate having multiple holes of a predetermined diameter; multiple ball-shaped beam-stops inserted into the holes; a second acrylic plate covering the entire upper part of the first acrylic plate; and a third acrylic plate covering the entire lower part of the first acrylic plate. The beam-stop array uses the ball-shaped beam-stops instead of tube-shaped beam-stops in order to measure a scattered ray value with a few errors regardless of image taking angle.
