Abstract
An X-ray detection system has a detector and a data acquisition unit. The detector detects an X-ray passing through a body and producing an analog electric signal for each channel. The data acquisition unit includes a plurality of circuit blocks each including as many circuits as the number of channels assigned to each block. The data acquisition unit converts the analog electric signal into a digital signal for each channel and outputs the resultant digital signal. A phase control unit controls the phase of the circuit blocks such that the circuit blocks are grouped into a plurality of groups. The respective groups operate in synchronization with clock signals for the data acquisition unit. Phases of the clock signals are mutually different at least between two groups.
