    摘要: The invention relates to a radiation detector (100), particularly for X-rays (X) and for γ-rays, which comprises a combination of (a) at least one primary conversion layer (101a-101f) with a low attenuation coefficient for the photons and (b) at least one secondary conversion layer (102) with a high attenuation coefficient for the photons. In preferred embodiments, the primary conversion layer (101a-101f) may be realized by a silicon layer coupled to associated energy-resolving counting electronics (111a-111f, 121). The secondary conversion layer (102) may be realized for example by CZT or GOS coupled to energy-resolving counting electronics or integrating electronics. Using primary conversion layers with low stopping power allows to build a stacked radiation detector (100) for spectral CT in which the counting rates of the layers are limited to feasible values without requiring unrealistic thin layers.

    摘要: The invention relates to an apparatus (10) for counting X-rayphotons (12, 14), in particular photons in a computer tomograph. The events from a first photon-sensitive element (20) are recorded in a first integrator (24), and the events coming from a second photon-sensitive element (22) are counted in a second integrator (26). A first summing unit (28) is provided for summing the values from the first and second integrators (24, 26) and a result signal to obtain a sum, wherein the result signal is obtained from a feedback device (30) being provided with the sum. It is there possible to reduce a total information density generated by the impinging photons (12, 14), so that a data stream with a reduced information density (or reduced data rate) is present at an output (34). The invention also relates to a corresponding imaging device (16) based on the detection of X-rayphotons (12, 14), in particular for medical use and to a method for counting X-rayphotons (12, 14), in particular photons in a computer tomograph.

    摘要: The present invention relates to an apparatus (10) for counting X-ray photons (12, 14). The apparatus (10) comprises a sensor (16) adapted to convert a photon (12, 14) into a charge pulse, a processing element (18) adapted to convert the charge pulse (51) into an electrical pulse (53) and a first discriminator (20) adapted to compare the electrical pulse (53) against a first threshold (TH1) and to output an event (55) if the first threshold (TH1) is exceeded. A first counter (22) counts these events (55), unless counting is inhibited by a first gating element (24). The first gating element (24) is activated when the first discriminator (20) outputs the event (55), and it is deactivated, when the processing of a photon (12, 14) is found to be complete or about to be completed by a measurement or by the knowledge about the time that it takes to process a photon (12, 14) in the processing element (18). By activating and deactivating the first counter (22) pile-up events, i.e. pile-up of multiple electrical pulses (53), can be addressed. The invention also relates to a corresponding imaging device and a corresponding method.
