Diagnostic installation for producing tomographic images
The installation comprises a support table for a patient, a plurality of x-ray sources or similar radiation sources, arranged in a series or planar array, with step-by-step activation of the radiation sources in any desired sequence. The beam of rays and the image field of the image detection installation are shifted in mutually opposite directions, so that sharply defined images are formed of only those details disposed in a specified longitudinal layer of the body as determined by the location of the rotational axis of the beam of rays. In the radiation path of the beam of rays of every radiation source, a beam path control device is arranged for shifting the beam path in relation to a central axis of the radiation source system and of the image pickup system, in dependence upon a laminographic height alteration. For example with plural circular arrays of x-ray sources about the central axis, the beam paths can be jointly adjusted by means of a single motor to intersect at any desired level within the patient receiving region of the support table.
