PROBLEM TO BE SOLVED: To improve efficiency of diagnosis based on multiple pieces of volume data.SOLUTION: An X-ray tube 13 generates an X-ray. An X-ray detector 14 detects the X-ray that is generated from the X-ray tube 13 and transmits through an analyte P. A rotary frame 11 continuously rotates the X-ray tube 13 and the X-ray detector 14 around the analyte P. A reconstruction part 34 reconstructs multiple pieces of time-series volume data with different scan time, with respect to a same scan region of the analyte P, on the basis of output from the X-ray detector 14. An image processing part 35 generates a single piece of volume data corresponding to a maximum value, an average value, a median value or a minimum value of the multiple pieces of reconstructed volume data in a temporal direction. The image processing part 35 generates the single piece of volume data on the basis of a piece of volume data out of multiple pieces of first volume data that pertains to a range in a prescribed period determined on the basis of a time density curve regarding a prescribed region of the pieces of volume data. |
