摘要： The invention relates to a radiation detector and a method for its production, wherein a series of converter plates (110) and interconnect layers (120), which extend into a border volume (BV) lateral of the converter plates (110), are stacked. By filling voids in the border volume (BV) with an underfill material and cutting through the border volume, a contact surface (CS) is generated in which electrical leads (123) of the interconnect layers (120) lie free. To allow a good contacting, said leads (123) are preferably provided with enlargements in the contact surface, for example by bonding wires (132) to them.

摘要： The invention relates to a radiation detector (100) comprising a converter element (113) with an array (120) of first electrodes (121) for sampling electrical signals generated by incident radiation (X). With a connection circuit (130), at least two first electrodes (121) can selectively be coupled to a common readout unit (141) according to a given connection pattern (CP1). The effective pixel size along the path of incident radiation (X) can thus be adapted to the distribution of electrical signals, which is usually determined by the spectral composition of the incident radiation.

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.
