  • System and method of computed tomography signal restoration via noise reduction
    Patent number: 10595808
    Abstract: An imaging system includes a computer programmed to estimate noise in computed tomography (CT) imaging data, correlate the noise estimation with neighboring CT imaging data to generate a weighting estimation based on the correlation, de-noise the CT imaging data based on the noise estimation and on the weighting, and reconstruct an image using the de-noised CT imaging data.
    Type: Grant
    Filed: June 29, 2016
    Date of Patent: March 24, 2020
    Assignee: GENERAL ELECTRIC COMPANY
    Inventors: Jiahua Fan, Meghan Lynn Yue, Jiang Hsieh, Roman Melnyk, Masatake Nukui, Yujiro Yazaki

  • X-ray CT apparatus
    Patent number: 8848860
    Abstract: An X-ray CT apparatus is provided. The X-ray CT apparatus includes an X-ray tube configured to apply an X-ray onto a subject, a scan device configured to rotate the X-ray tube about the subject to perform an X-ray CT scan, a first control device configured to switch an X-ray output of the X-ray tube from a first level to a second level smaller than the first level when the X-ray tube is placed at a first view angle, and configured to switch the X-ray output from the second level to the first level when the X-ray tube is placed at a second view angle, and a second control device configured to set the first view angle and the second view angle such that an X-ray exposure dose reduced by setting the X-ray output of the X-ray tube smaller than the first level becomes even on right and left sides.
