    摘要： An X-ray computer-tomography (CT) apparatus includes an X-ray detector, a reading unit, and a read control unit. The X-ray detector has a first region and a second region at least a part of which is aligned with the first region along a channel direction, the first region in which a plurality of first detection devices that detect X-rays are arranged, the second region in which a plurality of second detection devices having a width smaller in a slice direction than that of the first detection device are arranged. The reading unit reads a signal of the X-rays detected. The read control unit adjusts timing of reading signals from the first detection device and the second detection device according to difference between the size of the first and the second detection device in such a manner that time difference in the reading signals in the slice direction decreases.
