Publication number: 20070133737Abstract: To reduce a collimator thickness, plural collimators are not erected each independently on a scintillator array but are integrated into a collimator unit by molding with use of a plastic resin and the collimator unit is installed on the scintillator array. Even if the collimator thickness is made small, resulting in deterioration of the rigidity strength, there occurs no problem and thus the collimator thickness can be made as small as 200 ?m or less.Type: ApplicationFiled: December 7, 2006Publication date: June 14, 2007Inventors: Mitsuru Yahata, Katsumasa Nose
