Abstract
In an x-ray equipment stand designed to perform isocentric scanning movements and having three axes of rotation concurrent to the isocenter O, the isocenter can be caused to rotate about a fourth axis (Axis 4) perpendicular to the second axis (Axis 2) and parallel to the third axis (Axis 3). This permits displacement of the isocenter in the horizontal plane, especially along straight lines which are secant with the third axis.
