Abstract:
1. An X-ray CT apparatus comprising: an X-ray source configured to generate an X-ray; an X-ray detector configured to acquire an electric signal based on the X-ray; and a data acquisition system arranged on a side opposite to an X-ray incident side across the X-ray detector, the data acquisition system including a plurality of amp chips each amplifying the electric signal, and a plurality of A/D conversion chips each converting the amplified electric signal into a digital signal and outputting the digital signal to an image processing system, wherein the X-ray detector comprises: a collimator configured to absorb the X-ray; a plurality of scintillators configured to emit light resulting from incidence of the X-ray, the plurality of scintillators being provided so that a gap between adjacent scintillators of the plurality of scintillators is an extension of a gap between adjacent amp chips of the plurality of amp chips and of a gap between adjacent A/D conversion chips of the plurality of A/D conversion chips; a light reflector provided in a gap between adjacent scintillators of the plurality of scintillators; and a plurality of photodiodes configured to convert the light emitted by the plurality of scintillators into the electric signal.
