ON MACRO-STEREOANGIOGRAPHY : (OPTIMUM ANGLE OF DEVIATION FOR X-RAY TUBE) (II. Radiographic Technology for Stereoscopic Magnification)

Abstract

Because of the different inter-focal shifting distances, the macrostereoangiographic X-ray tubes developed recently by various makers, naturally have differences in depth, for example, in case of observations and differ in steric effect according to the observating condition, as well. Studies made of these issues revealed that the angle of deviation for X-ray tube was optimum for 2° to 3° and the magnification (M) was proportional to 1/M^<1.5>.
