Claim:
1. A CT device comprising an electron beam generation unit that comprises an electron gun, a deflection scanning unit and a restrictor, wherein the electron gun generates electron beams, the deflection scanning unit deflects the electron beams with a deflection direction varying as time so as to implement a circular scanning, and the restrictor has a plurality of circularly distributed holes, and wherein when the electron beams scan along the circularly distributed holes, a plurality of electron beams that are distributed circularly are output; a circular reflection target disposed to be coaxial with the circularly distributed electron beams, wherein the circularly distributed electron beams bombard the circular reflection target to generate X-rays that intersect the axis of the circularly distributed electron beams; and a circular detector array disposed to be coaxial with the circular reflection target and configured to include a plurality of detection units which receive the X-rays after they have passed through an object to be detected.
