    Abstract: An annular radiation receiver consisting of individual detectors, is stationary, and an X-ray source is rotated along a path surrounding the detectors. The individual detectors of the radiation receiver are combined into detector groups having an equal number of individual detectors, and the detector groups are adjustable independently of one another in such a fashion that those individual detectors which are disposed in advance of the radiography subject are respectively moved out of the X-ray beam. To this end, a cam plate can be present which is rotatable synchronously with the rotation of the X-ray beam, to which levers are coupled which control the detector groups.

    Abstract: In an illustrated embodiment, a ring-shaped X-ray source is operative to supply a fan-shaped X-ray beam from an incremental region thereof, successive incremental regions being sequentially activated to change the angular relationship between the beam and the subject. By way of example, three incremental regions equally spaced about the source ring may be simultaneously activated and then shifted in synchronism with the rotation of a collimator ring such that openings in the collimator ring are continually aligned with the active source regions, and collimator blades are continuously aligned with the active source regions so as to supply transmitted rays from each source region to a series of stationary detector elements. In the illustrated embodiment, the X-ray source regions and a detector ring are laterally offset from each other, and a diaphragm arrangement directs each beam at a slight angle so as to laterally bypass the adjacent portion of the detector ring while impinging on the receiving detectors. Motion of the collimator ring may be utilized to control shifting of the X-ray beams, so that such shifting is precisely synchronized with the movement of the collimator ring.

    Abstract: 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.

    Abstract: In an exemplary embodiment, a measuring arrangement comprises a radiation source emitting a radiation beam which penetrates the body layer to be examined, and a radiation receiver which supplies electrical output signals corresponding to the radiation intensity measured, a computer being connected with the radiation receiver for computing from the output signals of the radiation receiver the attenuation values of specific image points of the body layer. There is a collimator with a collimator grid forming a shielding compartment for each detector. Each detector is arranged in its collimator grid compartment and can be secured to a plate forming part of the grid, the plate being removably inserted in two parallel side portions forming the sides of each grid compartment. Furthermore, each plate with the detector secured thereto can project slightly beyond the radiation exit side of the side portions, so that a simple electrical connection to the detectors is possible.
