摘要： An imaging system includes a scintillator array (202) and a digital photomultiplier array (204). A photon counting channel (212), an integrating channel (210), and a moment generating channel (214) process the output signal of the digital photomultiplier array (204). A reconstructor (122) spectrally resolves the first, the second and the third output signals. In one embodiment, a controller (232) activates the photon counting channel (212) to process the digital signal only if a radiation flux is below a predetermined threshold. An imaging system includes at least one direct conversion layer (302) and at least two scintillator layers (304) and corresponding photosensors (306). A photon counting channel (212) processes an output of the at least one direct conversion layer (302), and an integrating channel (210) and a moment generating channel (214) process respective outputs of the photosensors (306). A reconstructor (122) spectrally resolves the first, the second and the third output signals.

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 a method for controlling the transmission power employed by a transmitting unit for transmitting multicast signals via a radio interface to communication devices of a multicast group using a single physical channel. In order to enable an efficient power control, it is proposed that at least the communication device receiving the weakest multicast signals transmits power control commands to the transmitting unit. Further, it is proposed that the transmitting unit adjusts the transmission power based on power control commands received from at least one of the communication devices in a way that the power control commands of the communication device receiving the multicast signals with the lowest quality have the most significant influence on the adjustment. The invention relates equally to a corresponding transmitting unit, to a corresponding communication device and to a corresponding communication system.

摘要： A radiation detector(16) having a first detector layer (24) and a second detector layer (26) encircles an examination region (14). Detectors of the first layer include scintillators (72) and light detectors (74), such as avalanche photodiodes. The detectors of the second detector layer (26) include scintillators (62) and optical detectors (64). The scintillators (72) of the first layer have a smaller cross-section than the scintillators (62) of the second layers. A group, e.g., nine, of the first layer scintillators (72) overlay each second group scintillator (62). In a CT mode, detectors of the first layer detect transmission radiation to generate a CT image with a relatively high resolution and the detectors of the second layer detect PET or SPECT radiation to generate nuclear data for reconstruction into a lower resolution emission image. Because the detectors of the first and second layers are aligned, the transmission and emission images are inherently aligned.

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.

摘要： The invention relates to a radiation detector (200), particularly an X-ray detector, which comprises at least one sensitive layer (212) for the conversion of incident photons (X) into electrical signals. A two-dimensional array of electrodes (213) is located on the front side of the sensitive layer (212), while its back side carries a counter- electrode (211). The size of the electrodes (213) may vary in radiation direction (y) for adapting the counting workload of the electrodes. Moreover, the position of the electrodes (213) with respect to the radiation direction (y) provides information about the energy of the detected photons (X).

摘要： The invention relates to a radiation detector, particularly an X-ray detector (100), comprising a counting circuitry (10, 20, 30) for counting electrical pulses generated by the (sub-)pixels (2) of the detector. In the counting circuitry, the results counted by a fast counting stage (10) are at intervals transferred to a slow counting stage (20). The fast counting stage (10) may for example comprise a fast counter (111) with a low bit-depth operating as a frequency divider in front of a slow counter (121) of high bit-depth in the slow counting stage (20). The counting circuitry (10, 20, 30) can optionally be fed via a multiplexer (4) with the signals of several (sub-)pixels (2). Furthermore, the pixels (1, 2) of the radiation device may optionally deliver energy resolved pulses.

摘要： The invention relates to a system and a method for payment of a parking fee for a motor vehicle (11). The method comprises the steps of: transmitting (21, 31) an identification code by the driver to a central parking terminal (12) by use of a mobile communication terminal (13); registering (22, 32) a time of transmitting and the identification code within the central parking terminal (12); charging of parking fee onto an account of a mobile communication terminal (13) depending on the identification code; transmitting (24, 33) a registration data unit from the central parking terminal (12) to the mobile communication terminal (13) of the driver; transmitting (26, 35) the registration data unit from the mobile communication terminal (13) to a receiving device (14) located in the motor vehicle (11) or associated to the parking slot (15) and storing (25, 36) the registration data unit in the receiving device (14). By retransmitting a registration data unit to the mobile communication terminal (13) the registration data unit can be signaled to a traffic warden (17). This provides the advantage that the traffic warden (17) may issue a parking fine ticket to the motor vehicle (11) at the moment of checking. A further advantage is that the communication effort is reduced for the traffic warden (17). So the number of motor vehicles (11) which may be checked in a certain amount of time is increased in comparison to the situation where the traffic warden (17) has to contact a central parking terminal (12) for each motor vehicle (11) separately.
