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.
