Abstract:
1. An X-ray CT scanner comprising: a setting section which sets first and second times defining a first image creation time zone in a pre-stored first CT value change curve which is a statistical representation of how the inside of a subject is dyed with a contrast agent as a function of time, the first CT value change curve having a peak; an X-ray tube which generates X-rays toward a subject to perform scanning after the first image creation time zone is set by the setting section; an X-ray detector which detects the X-ray generated by the X-ray tube and passing through the subject in which a contrast agent is injected, and converts the detected X-ray into an electric signal; generating section which generates a real time second CT value change curve associated with the subject based on the electric signal; a specifying section which combines the first CT value change curve and the second CT value change curve to specify third and fourth times defining a second image creation time zone in the second CT value change curve, the third and fourth times defining the second image creation time zone in the second CT value change curve corresponding to the first and second times defining the first image creation time zone; and a creating section which creates an image based on X-rays detected in the second image creation time zone.
