PROBLEM TO BE SOLVED: To provide an X-ray CT system by which a proper scanogram image can be acquired by expanding the photographing range of the scanogram image. SOLUTION: This X-ray CT system includes: an X-ray source 101S which irradiates a subject with X ray; an X-ray detecting instrument 106S which is arranged to be confronted with the X-ray source, and detects the X ray which has permeated the subject; a bed 105 which moves the subject who is arranged between the X-ray source and the X-ray detecting instrument in the body axial direction of the subject; and a scanogram image forming means which makes the X-ray source cast the X ray to the subject, collects the X ray permeated the subject which has been detected by the X-ray detecting instrument as X-ray permeation data, and forms the scanogram image of the subject conforming to the collected X-ray permeation data. The scanogram image forming means controls the timing for collecting the X-ray permeation data in response to the moving speed of the bed. COPYRIGHT: (C)2011,JPO&INPIT |
