Claim Text:
1. An X-ray CT imaging device, comprising: a revolution section that causes an X-ray generation source and an electric X-ray detector, facing each other while having a subject therebetween, to revolve about a revolution shaft as a center of revolution; a revolution driving section that drives driving the revolution section to revolve with respect to the subject; an X-ray radiation area setting section that accepts a setting of a local area of the subject as an X-ray radiation area; a control section that controls at least the revolution driving section; and a high sensitivity site specification section to specify a high sensitivity site in a biological body that is highly sensitive to an X-ray; wherein the revolution section is revolved with respect to the X-ray radiation area to perform CT imaging; and wherein, when radiation of an X-ray flux in a revolving movement is performed during the CT imaging in accordance with the X-ray radiation area accepted by the X-ray radiation area setting section, the control section controls at least one of an X-ray revolution plane formed by the X-ray flux along with the revolution of the revolution section, and a revolution range of the revolution section, such that an amount of X-ray radiation toward the high sensitivity site is decreased.
