Abstract
There are many cases of X-ray graphy as ordinary work, in which the X-ray beam is inclined for the both direction of longitude and latitude. When we interpret the explanation or the illustration of such a double angle X-ray graphy, we can not get only one construction but a few it is an undesirable. We studied about such a problem, and considered with the mechanism of X-ray tube rotation and the right X-ray beam centering.
