Abstract: The invention relates to a radiation detector (100), particularly for X-rays (X) and for ?-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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a detection device (6) for detecting photons emitted by a radiation source (2). A signal generation unit (20) generates a detection signal indicative of the energy of a detected photon while photons strike the detection device (6),and a baseline signal, which is affected by photons that previously struck the detection device (6),while photons are prevented from striking the detection device (6). A baseline shift determination unit (40) determines a baseline shift of the detection signal depending on the baseline signal. An energy determination unit (30) determines the energy of a detected photon depending on the detection signal and the determined baseline shift. Since the baseline shift of the detection signal is determined from a baseline signal that is generated while photons are prevented from striking the detection device (6), the baseline shift can be determined with higher accuracy, resulting in an improved energy determination.
