摘要： In an exemplary embodiment, a measuring arrangement for irradiating the examination subject from different directions has a radiation source, a radiation receiver, and a computer connected to the radiation receiver for computing the attenuation values of specific image points of the irradiated body layer from the output signals of the radiation receiver. A collimator is present with a collimator grid compartment for each detector of the radiation receiver. Every detector is comprised of a scintillator crystal and a photoelectric transducer. The scintillator crystal is mounted on the surface of the photoelectric transducer such that the transducer is disposed between the associated collimator plate and the scintillator crystal. The scintillator crystal is coated, on its surface, with the exception of the surface confronting the photoelectric transducer, with an optical seal which can be light-reflecting on its side resting against the scintillator crystal.

摘要： In the exemplary embodiments, a ring made of light-conductive material curved around the center of rotation is provided, onto the surface of which a light source radiates, which emits light signals corresponding to the signals to be transmitted. The light-conductive ring is formed in such a manner that it passes on the incident light over its entire periphery and has at least one point of interruption on which a light receiver is arranged. The invention is particularly suited for use in a computer-tomograph, in which an x-ray source and a detector for scanning the radiography subject at different projections rotate around the radiography subject, and data processing equipment determine an image of the examined transverse layer of the radiography subject from the detector signals. In this case the light-conductive ring can transmit the detector signals to the stationary part.
