    • A hot axial pressing method for sintering a ceramic powder, particularly doped Gd2O2S, comprises the step of placing a first porous body (7), the ceramic powder (9) and a second porous body (7) into a mould shell (5) supported by a support (13, 14). The ceramic powder (9) is located between the porous bodies (7). Gaseous components are evacuated from the ceramic powder (9) up to an ambient pressure of less than 0.8 bar. The porous body (7) and the ceramic powder (9) are heated to a maximum temperature of at least 900° C. and are applied to a pressure up to a maximum pressure of at least 75 Mpa. According to the invention the variation in time of the heating step and the variation in time of the pressure applying step is adjusted to each other such that the mould shell 5 is held by the porous bodies (7) and/or the ceramic powder (9) in a state where the mould shell (5) and the support (13, 14) are disconnected with respect to each other.

    • 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.
    • 本发明涉及一种用于计数X射线光子(12,14)的装置(10)。 所述设备(10)包括适于将光子(12,14)转换为充电脉冲的传感器(16),适于将所述充电脉冲(51)转换成电脉冲(53)的处理元件(18) 适于比较电脉冲(53)与第一阈值(TH1)并且如果超过第一阈值(TH1)则输出事件(55)的第一鉴别器(20)。 第一计数器(22)对这些事件(55)进行计数,除非由第一选通元件(24)抑制计数。 当第一鉴别器(20)输出事件(55)时,第一选通元件(24)被激活,并且当发现光子(12,14)的处理完成或将要由 测量或通过关于在处理元件(18)中处理光子(12,14)所需的时间的知识。 通过激活和去激活第一计数器(22)堆积事件,即堆叠多个电脉冲(53),可以被解决。 本发明还涉及相应的成像装置和相应的方法。
