1. An X-ray computed tomography apparatus, comprising:
an X-ray detector including a plurality of detection elements arranged in a plurality of rows at least in a channel direction, the channel direction being orthogonal to a column direction; and
processing circuitry configured to
acquire an estimated count number of X-rays incident on the X-ray detector for each of the plurality of detection elements, and
determine a bit number for transmission for detection data indicating a count number of each of the plurality of detection elements based on the estimated count number,
wherein the processing circuitry is further configured to designate, as a most significant bit for transmission, a bit position according to the estimated count number other than a most significant bit included in bits of the detection data to determine the bit number for transmission.
