X-ray CT apparatus and processing method therefor |
摘要 |
With the object of improving image quality while keeping short the time taken to reconstruct the first X-ray tomogram at the time of start of scanning in its real-time display mode, an X-ray CT apparatus having a rotary unit for causing an X-ray source and an X-ray detector for detecting X-rays from the X-ray source to rotate integrally around a subject, is provided with a full data reconstructing device for reconstructing tomograms on the basis of penetrating X-ray data of each view detected during a full turn around the subject, a segment data reconstructing device for reconstructing tomograms on the basis of penetrating X-ray data of each view detected during a turn by (180+alpha) degrees, and a change-over device for counting the tomograms reconstructed after the start of scanning, and changing over between the full data reconstructing device and segment data reconstructing device according to the count.
