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： Systems and methods for data acquisition in computed tomography (CT) applications are provided. The systems and methods are particularly adapted for scanning and acquiring/processing data in connection with high-power cone-beam CT applications. The electron beam is moved/scanned along the anode surface to multiple focal positions. Data acquisition for a full projection at one focus position and one view angle is achieved by activating each focus position multiple times during the data acquisition for one angle of the gantry. The detector array and associated data processing system are adapted to rapidly switch between the different focus positions during the acquisitions for one view angle and to collect all data belonging to the same projection into the same data set. Adaptive electron optics are utilized to move/scan the electron beam along the anode surface to the various focus positions. Alternatively, a plurality of cathodes may be provided for respective focus positions and the system may support fast switching therebetween to achieve desirably short spot times. The disclosed CT system permits greater power densities without risk of heat damage to the anode and effectively increases the track velocity of the electron beam on the anode surface. The CT system and associated data acquisition methods have particular utility in CT applications requiring increased time resolution and/or spatial resolution, e.g., cardiac CT applications.

摘要： The invention is directed at an apparatus (10), an imaging device and a method for detecting X-ray photons, in particular photons (32,34) in a computer tomograph. Photons (32,34) are converted into an electrical pulse and compared against a threshold using a discriminator (20). The electrical network (12) performing these functions comprises a switching element (28), that can modify the electrical path (22) along which the process signals travel. The trigger signal (V T ) for actuating the switching element (28) is derived from an electrical state of the electrical path (22). If a pulse associated to a photon (32,34) is detected, the switching element (28) is actuated in order to avoid that the processing of the charge pulse stemming from a first photon (32) is affected by a subsequent second photon (34).
摘要翻译：本发明涉及一种用于检测计算机断层摄影机中的X射线光子，特别是光子（32,34）的成像装置和方法的装置（10）。光子（32,34）被转换成电脉冲，并使用鉴别器（20）与阈值进行比较。执行这些功能的电网（12）包括开关元件（28），其可以修改过程信号沿其移动的电路径（22）。用于致动开关元件（28）的触发信号（V SUB T）是从电路径（22）的电气状态导出的。如果检测到与光子（32,34）相关联的脉冲，则开关元件（28）被致动以避免由第一光子（32）产生的电荷脉冲的处理受随后的第二光子（ 34）。

摘要： Due to NACK-to-ACK misinterpretations in base stations, packets are lost, and there may be gaps in a re-ordering buffer of a base station. According to the present invention, when the receiver decodes - possibly after some retransmissions - a first data packet without an error, which first data packet is sent along with an indicator indicating that the first data packet is a new data packet, after the receiver has sent a negative confirmation message (NACK) with respect to a second data packet, the receiver sends a Revert (REV) message to the transmitter. The REV message informs the base station that the first data packet was decoded error-free, and that the second data packet is still missing on the receiving side so that the base station may re-send this second data packet.
摘要翻译：由于基站中的NACK到ACK的误解，分组丢失，并且在基站的重新排序缓冲器中可能存在间隙。根据本发明，当接收机可能在一些重传之后解码第一数据分组而没有错误时，哪个第一数据分组与指示第一数据分组是新数据分组的指示符一起发送，在接收机具有发送关于第二数据分组的否定确认消息（NACK），接收机向发射机发送恢复（REV）消息。 REV消息通知基站第一数据分组被解码为无错误，并且第二数据分组在接收侧仍然丢失，使得基站可以重新发送该第二数据分组。

摘要： In case a transmission of a MAC-hs PDU is aborted and all the RLC PDUs contained therein are discarded, delays may occur since these lost PDUs have to be retransmitted on RLC protocol level resulting in considerable delay since the Iub and Iur text interfaces have to be passed. According to an exemplary embodiment of the present invention, a transmission abortion is determined and a reduced number of data packets contained in the container which transmission has been aborted are put into another container provided with the same sequence as the proceeding aborted container and sent to the receiver. Advantageously, due to the fact that this second container may have a reduced amount of data packets contained and/or may have a reduced length, a probability that this second container is received error free at the receiving side is increased.
摘要翻译：在MAC-hs PDU的传输被中止并且包含在其中的所有RLC PDU被丢弃的情况下，可能发生延迟，因为这些丢失的PDU必须在RLC协议级别上重传，导致相当大的延迟，因为Iub和Iur文本接口必须通过。根据本发明的一个示例性实施例，确定传输中止，并且包含在已经中止传输的容器中的数据包的数量减少被放入具有与正在进行的中止容器相同的序列的另一个容器中，并被发送到接收器。有利的是，由于第二容器可以具有减少的数据分组容量和/或可以具有减小的长度的事实，所以增加了在接收端接收到第二容器没有错误的概率。

摘要： The invention relates to a radiation detector (100) and an associated method for the detection of (e.g. X or ?-) radiation. The detector (100) comprises a converter element (110) in which incident photons (X) are converted into electrical signals, and an array of anodes (130) for generating an electrical field (E) in the converter element (110). At least two anodes are associated with two steering electrodes (140) to which different potentials can be applied by a control unit (150). Preferably, each single anode or small group of anodes is surrounded by one steering electrode. The potentials of the steering electrodes (140) may be set as a function of the potentials that are induced in these electrodes when an operating voltage is applied between the anodes and a cathode (120). Moreover, a grid electrode (160) may be provided that at least partially encircles anodes (130) and their steering electrodes (140).
