STUDY ON THE AUANTITATIVE INDICATION FOR THE THICKNESS OF THE TRANSVERSE SECTION OF TOMOGRAPHY APPARATUS

Abstract

The various kinds of tomography appartus has appeared having various movement machinary. The tomography has been used more and more for various field. However, the auantitative indication for the thickness of the transverse section has not been made, although it is necessary for the accurate use of tomography apparatus. The authors made for trial various kinds of chart and examined several apparatsus whose movement are different and the movement-angle of x-ray tube and the thickness of the transverse section. They found out the simple and common auantitative indication for the thickness of transverse section based on these results. Furthermore, they studied the blackihg of the photography by using charts.
