PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus and an X-ray CT imaging method capable of improving quality of a scanography image.SOLUTION: An X-ray CT apparatus includes an X-ray tube, a first detector, a plurality of second detectors, and a processing circuit. The X-ray tube irradiates an X-ray, the first detector is arranged at a position opposed to the X-ray tube with a subject in between, and rotates with the X-ray tube by a rotary frame. The plurality of second detectors arranged between the subject and the first detector are photon counting type detectors fixed along the rotation track of the rotary frame. The processing circuit performs first scanning and creates first data from the first detector, specifies a plurality of first channels which are detector positions based on the first data, and creates a scanogram image based on a positional relationship of the X-ray tube, the first detector, and the plurality of second detectors, and information on the plurality of first channels.SELECTED DRAWING: Figure 1 |
