A 3D display equipped with a linearly moving mirror reflecting a series of 2D cross sections pictures has been devised. The pictures were displayed by a CRT in perfect synchronization with the back-and-forth movements of the mirror. The 80×80×80 mm3 3D space contained 128×128 pixels; with each pixel having 256 grades of intensity, enough to produce a satisfactory 3D image of an ultrasonic echogram of hepatic vessels. The images can be observed from different angles by changing the observer's position or by prompt rotation of the image through a console. Mechanical problems inherent in using moving parts have been solved
