In the exemplary embodiments a layer is to be scanned which is generally parallel to the longitudinal axis of the patient support. For example, a radiation source and a radiation receiver may be rotated in an arc about a rotational axis which lies perpendicular to the longitudinal axis of the patient support to scan a layer area in such a way that the scanned layer within the exposure subject is traversed exclusively along beam paths each of which is crossed along its entire length in the subject by a multitude of other beam paths.

Radiation diagnostic device for generating tomographic images

An X-ray examination apparatus, including an adjustable optical X-ray diaphragm or focusing means; and an examination table having a cassette drawer carriage displaceable along the examination table located directly below the patient support platform of the examination table, and a cassette drawer which is insertable into the cassette drawer carriage having two pairs of clamping members each with two mutually oppositely movably adjustable clamping jaws for the retention of the X-ray film cassettes inserted into the cassette drawer. In an X-ray examination apparatus of the above-mentioned type, each clamping jaw pair is itself displaceable within the cassette drawer in the two adjusting directions for the associated clamping jaws, at the clamping of an X-ray film cassette in the cassette drawer, pursuant to the selected film division. Thereby, it becomes possible that also larger film formats can be rationally employed, and to be able to combine a plurality of X-ray exposures or photographs of a patient on a single film plate. The manipulation of the cassette drawer is rendered particularly easy when a motorized adjustment of the clamping jaw pairs is provided for in dependence upon the selected film division or partitioning program, and the particular division sections. In this instance, a plurality of X-ray exposures may be initiated within time intervals of a few seconds.
