Abstract

An X-ray xuality and quantity calibration among more than two X-ray apparatus is indispensable for accomplishment to the standardization of radiographic exposure technic. In order to obtain the same X-ray out put auther recommend following method. On the basis of a kV-chart the standard transmission characteristic of X-ray at a certain X-ray tube current as 100mA is created. After measuring an X-ray transmission curve of the apparatus to be calibrated the same condition these two curves are superimposed and determined how they are differed each other. Error of subject tube voltage is estimated from the deviation on the curve.
