An analysis was made of the geometric relation between stero-radiographing system and its observation one which has an effect on the imaging in the diagnostic stereography. (1) In stereography with magnified X-rays in which the magnification ratio of images on X and Y axis is different from the one on Z axis a kind of image distortion is inevitable. (2) Stereographing system under a certain appropriate condition can produce an image with equal magnification ratio of one on X, Y and also Z giving life-size without distortion. (3) As discribed above, a magnified stereographic image accompanies a distortion. However, a magnified stereographic image will be perceived if the image on the retina is enlarged, which can be obtained by shortening the visual distance thus widening the visual angle.
