Multi-slice X-ray computed tomography apparatus



Multi-slice X-ray computed tomography apparatus



Official Gazette of the United States Patent & Trademark Office Patents 1285(4), Aug 24



An X-ray computed tomography apparatus, comprises an X-ray generator, an X-ray detector, a controller, and a display. The X-ray generator is configured to generate a first X-ray in a pre-scan mode and a second X-ray in an image scan mode. The X-ray detector is 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. The X-ray detector is further configured 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 is narrower than the second exposure width. The controller is configured to control the first scanning position and the second scanning position. The display is 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.
