<p><P>PROBLEM TO BE SOLVED: To provide an X-ray computed tomography device which allows shifting from monitoring scanning to real scanning at a timing with a contrast effect being good. <P>SOLUTION: A scanning mechanism 10 carries out CT-scanning to a subject injected with a contrast medium and collects sequential projection data on the subject. An image-generating part 34 generates data of a sequential CT image on the subject based on the collected sequential projection data. An ROI setting part 36 sets an area of interest on the generated sequential CT image. A time-concentration curve-generating part 38 generates a time-concentration curve regarding the set area of interest based on the data of the sequential CT image. A determination part 42 determines whether to continue the monitoring scanning by the scanning mechanism 10 or to carry out the real scanning by the scanning mechanism 10. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
