PROBLEM TO BE SOLVED: To obtain a high quality image of a subject that move periodically with time-wise high resolution and reorganize even with a computerized tomograph. SOLUTION: A detection unit 2 has one initial detector line and a final detector line, the detector lines extends nearly vertically to a rotation axis 6, a holder 7 rotates around the rotation axis 6 with the number of rotation (n), the presence of a static phase is obtained, and one measurement data set geared to the then rotation angle α simultaneously by the detector lines for each rotation angle α in many rotation angles is obtained during the static phase. And the duration of the static phase is determined, the number of rotation (n) is selected so that the holder 7 may rotate by a rotation angle γ close to the range β of reorganization angles necessary to reorganize the image of a subject 9 during the static phase, thereby reorganizing the image of the subject 9 using a 3D back projection algorithm from the measurement data set. |
