Abstract: In order to manufacture a scintillator layer for a detector for the detection of electromagnetic radiation, transmitted by an object, which has a high spatial resolution and only a slight interaction between the scintillator elements, it is proposed to pour a molten mass of a radiation-absorbing metal, having a melting point below 350° C., into intermediate spaces which extend vertically between neighboring scintillator elements.

Abstract: The invention relates to a computer tomograph provided with a charge-integrating read amplifier having a plurality of gain factors for a data acquisition system as well as a control circuit for the gain factor. In order to avoid noise in addition to the shot noise in computer tomographs of this kind and also to avoid degrading of the DQE (Detection Quantum Efficiency), according to the invention it is proposed that the control circuit automatically selects the gain factor in dependence on the expected integrated input signal of the next frame, the expectation being based on the maximum possible relative variation of the integrated input signal between two successive frames.

Abstract: A data acquisition system which includes data generating and processing units ( 1 a , 1 b , 1 c), each of which includes a respective data source ( 3 a 1, 3 a 2, 3 b 1, 3 c 1 ) which serves to generate data. The data each time generated is processed by means of associated data processing means ( 2 a , 2 b , 2 c 11 a 1, 11 a 2, 12 a 1, 12 a 2, 13 a 1, 13 a 2 ) in such a manner that each time a digital data word which comprises at least two bits is presented for output. The output of the digital data words takes place in synchronous-parallel fashion in dependence on first control signals ( 4, 5 ). Shift registers ( 6 a , 6 b , 6 c) which are coupled to one another so as to form a chain propagate the digital data words in synchronous-parallel fashion in dependence on second control signals ( 7, 8 ) and are coupled to a respective associated data generating and processing unit ( 1 a , 1 b , 1 c).
