Abstract

PURPOSE:To allow the central part of a specimen to be always present at the central part of a wedge, by employing such a structure that the wedge moves before, behind, left and right without rotation. CONSTITUTION:The outside of a specimen 45 is surrounded by a clindrical enclosure 44 to insert the specimen 45 in the circular hole provided to the center of a rectangular wedge 43 in a rotatable manner. This wedge 43 moves in a before-and-behind direction and a left-and-right direction with the rotation of the specimen 45 due to the rotation of a specimen turntable 47 so as not to obstruct the rotation of the specimen. By comparing radiation transmitting data when there are the specimen 45 and the cylindrical enclosure 44 with the preliminarily measured radiation transmitting data of the wedge 43 and a water phantom, linear absorption coeffecient based on the specimen 45 and the water in the cylindrical enclosure 44 can be measured.
