A working mechanism for moving a treatment table including an expandable and contractable pneumatic spring coupled to the table, a pneumatic control pressure circuit for controlling the expansion and contraction of the pneumatic spring and a hydraulic checker coupled to the treatment table whereby the treatment table is smoothly moved and maintained at any heighth.

Working mechanism for a treatment table

Method and apparatus for making a tomogram according to this invention include one elongated support member supporting an X-ray tube and a film device in an opposed relation with each other at both ends thereof and one vertical shaft supporting the elongated support member thereon. Movement of the axis of the shaft along a desired curve results in the movement of an X-ray beam in the state of the X-ray beam intersecting the curve. In the meantime, an angle of rotation around the axis of the shaft is adjusted so as to maintain an angle of intersection of the X-ray beam with the curve at a predetermined angle. A film surface is moved relatively with respect to the X-ray beam so as to allow the beam to scan the film surface. The velocity of movement of the film surface is synchronized with the movement of the shaft. In the invention, the aforementioned movement of the shaft along the curve, the aforementioned angle of rotation of the shaft and the aforementioned movement of the film surface are respectively controlled or adjusted by digital signals.
