    • The disclosure has one object to provide a radiation tomography apparatus of a low price that facilitates a design change of a detector ring to suppress costs of development. The radiation tomography apparatus according to the disclosure includes a plurality of modules configured to receive detected data from different radiation detectors. Then, the modules each send and receive the detected data to and from one another, thereby sharing the detected data and counting the number of coincidence events. That is, when manufacturing radiation tomography apparatus, merely wiring the coincidence modules achieves implementation of the coincidence unit. This allows manufacturing the radiation tomography apparatus without new development of a substrate for performing coincidence. Consequently, the radiation tomography apparatus of a low price can be provided with suppressed costs of the development.
    • 本发明的一个目的是提供一种低价格的放射线断层摄影装置,其便于检测器环的设计改变以抑制显影成本。 根据本公开的放射线断层摄影装置包括被配置为从不同的辐射检测器接收检测到的数据的多个模块。 然后,模块各自发送并接收检测到的数据到彼此,从而共享检测到的数据并对重合事件的数量进行计数。 也就是说,当制造放射线断层摄影装置时,仅仅配合符合模块实现了重合单元的实现。 这允许制造放射线断层摄影装置,而不需要用于执行重合的基板的新开​​发。 因此,可以提供低价格的放射线断层摄影装置抑制开发成本。

    • According to a spurious pulse generator of this invention, integrating circuits are provided at a plurality of stages for carrying out integrating operations about time and outputting a spurious pulse, the integrating circuits being constructed to input a voltage value for controlling a crest value which is a peak swing of the spurious pulse to an amplifier forming an integrating circuit at a most upstream stage when a switching element is ON, and to input a constant voltage value when the switching element is OFF. As a result, the voltage value before ON-state and after ON-state of the switching element does not change but remains a constant voltage value, thereby obtaining a desired spurious pulse.
