PROBLEM TO BE SOLVED: To realize decrease of downtime and service man-hours which are caused when exchanging DAS (data acquisition system) boards. SOLUTION: The data acquisition system which processes signals detected by an X-ray detector and transfers the signals to an X-ray computed tomograph body, is equipped with a plurality of DAS boards each provided with signal processing multi-channel circuits each including an amplifier 19, a integrator 20, and an analog-to-digital converter 21, with a plurality of connectors 18 which detachably connect the plurality of DAS boards 16, and with corrective units 23, 24, 25 which correct output from the signal processing circuits and which are connected to the plurality of DAS boards through the plurality of connectors, while each of the plurality of DAS boards 16 is provided with a memory 17 which stores data to match with input-output characteristics of the plurality of signal processing circuits provided in the respective DAS board, and the corrective units correct the output from the signal processing circuits based on the data stored in the memory 17.
