Classification: A61B

Abstract:
An X-ray computed tomography apparatus, comprising:an X-ray generator configured to generate a first X-ray in a pre-scan mode and a second X-ray in an image scan mode; an X-ray detector configured to detect a first transmission X-ray exposed through a specimen to a first exposure width of the X-ray detector along a body axis of the specimen, resulting from the first X-ray at a first scanning position in the pre-scan mode and to detect a second transmission X-ray exposed through the specimen to a second exposure width of the X-ray detector along the body axis of the specimen, resulting from the second X-ray at a second scanning position in the image scan mode, the first exposure width being narrower than the second exposure width; a controller configured to control the first scanning position and the second scanning position; and a display configured to display a first image based on the first transmission X-ray detected by the X-ray detector and a second image based on the second transmission X-ray detected by the X-ray detector.
