ABSTRACT:
In order to solve handling problems which arise during use of a mammograph, the x-ray tube of the mammograph is carried by the end of an arm which rotates about an axis at right angles to the arm. The other elements of the mammograph are carried by another arm which is placed in a plane parallel to the plane of rotation of the first arm and rotates about the same axis. It is shown that, by moving the image receiver away from the breast support plate and by utilizing a parallax effect, it is possible to take stereotaxic photographs without entailing any need to displace either the breast support plate or the image receiver or even a radiation-sensitive film placed in a stationary position within the image receiver.
