Tomograph for producing transverse layer images

DETAILED DESCRIPTION The object underlying the invention is to develop a tomograph of the type specified at the outset with regard to its construction such as to render possible rapid movement of the X-ray source for scanning an exposure subject and thus render possible a short image build-up time.
According to the invention, this object is achieved by the fact that the structural elements of the X-ray generator on the high voltage side are disposed in an oil-filled tank mounted on the rotating frame, that for the transfer of energy a rotating current coupling is provided between the rotating frame and a stationary energy supply installation and that the anode of the X-ray tube is earthed (connected to ground).
In the tomograph according to the invention, there is no need to run high voltage cables to the X-ray source.
The coupling between the generator parts disposed on the rotary mounting and the energy supply installation may be made, by way of example, via a brush-slip ring arrangement.
When the X-ray source is moved, therefore, there are no heavy cables to be moved with it, so that very short image build-up times are possible.
Because the anode of the X-ray tube is earthed (grounded), the rays can issue near the end of the X-ray tube housing, in the case of an X-ray tube housing of small design, which means the tomograph of the type according to the invention has an advantageous mechanical construction.
The invention is explained in detail below with reference to an embodiment represented in the drawings; and other objects, features and advantages will be apparent from this detailed disclosure.
