PROBLEM TO BE SOLVED: To provide a computed tomography system etc. in which an X-ray dose for exposing a subject is reduced upon acquiring data showing changes of the subject for a predetermined time. SOLUTION: The computed tomography system (10) includes a gantry (14) configured to rotate around an object (26), an X-ray source (18) mounted on the gantry (14), a table (16) supporting the object (26), and a controller (22). The controller (22) is configured to acquire a first imperfect view set of the object (26) during a first helical pass and a second imperfect view set of the object (26) during a second helical pass. The controller (22) is configured to form an image based on both the first imperfect view set and the second imperfect view set. COPYRIGHT: (C)2010,JPO&INPIT |
