    摘要: The invention relates to an X-ray detector for detecting X-radiation, as used, in particular, in computer tomographic (CT) systems. The X-ray detector in accordance with the invention is composed of a photo sensor device, which comprises individual detector elements (1), above which scintillator elements (2) are disposed. These convert the incident X-ray light (6) into visible or UV light (7), which is detected by a photodiode (4) located on the detector element (1). In accordance with the invention, a micro-lens (3), which focuses the light (7) departing from the scintillator element (2) onto the photodiode (4), is disposed between the scintillator element (2) and the detector element (1). It is possible, in this manner, to use large areas of the detector element (1) for further electronic components (5) outside the photodiode (4), and, at the same time, to ensure a high DQE (Detection Quantum Efficiency) in that the light (7) departing from the scintillator element (2) is virtually fully exploited. The crosstalk from scatter radiation from adjacent detector elements is effectively prevented simultaneously.

    摘要: A data acquisition system which includes data generating and processing units (1a, 1b, 1c), each of which includes a respective data source (3a1, 3a2, 3b1, 3c1) which serves to generate data. The data each time generated is processed by means of associated data processing means (2a, 2b, 2c 11a1, 11a2, 12a1, 12a2, 13a1, 13a2) 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 (6a, 6b, 6c) 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 (1a, 1b, 1c).
