A multiple cathode X-ray tube for densitometers. This tube contains an anode assembly functioning by transmission, which is arranged along the sides of a regular convex polygon, with several cathodes, each of which sweeps one side of the polygon and a collimation device with several openings placed in front of the anode assembly to produce a series of fine, parallel and coplanar beams, the number of beams being equal to the number of openings. Such a tube makes very fast tomography possible.

Multiple cathode X-ray tube for densitometers

A hollow, cylindrical, rotating anode, X-ray tube for tomodensitometers. This tube contains a bell-shaped, hollow, cylindrical anode functioning by transmission, which is swept on its inner surface by an electron beam and produces in cooperation with a collimation device having several openings a series of fine X-ray beams, which are roughly parallel and coplanar, the number of these beams being equal to the number of openings in the collimation device. Such a tube makes very fast tomography possible.
