- 摘要：
To provide an X-ray CT scanner that shortens the time required for reducing an artefact between high X-ray absorbent materials.
SOLUTION: The X-ray CT scanner is provided with an X-ray source to irradiate X rays to a subject, an X-ray detector arranged opposite to the X-ray source and giving the output of X-ray image data based ON the X-ray penetrating the subject and an X-ray image reconstruction means to produce an X-ray CT image from the image data obtained by the rotation of the X-ray source and X-ray detector. In the case when the subject includes at least a pair of high X-ray absorbent materials likely to produce artefact ON its images, the image data itself is provided with a detection means to detect the differences of the X-ray source from the X-ray detector used for the subject and an artefact correction means that prepares the X-ray CT image in the image data detection region extended up to the region including one X-ray absorbent material in response to the differences obtained by the detection means and corrects the artefact generated across the pair of high X-ray absorbent materials based ON the prepared X-ray CT image.
