  • Patent number: 10555724
    Abstract: An ultrasound probe calibration system and method. The system comprises an ultrasound probe calibration phantom (100), and the ultrasound probe calibration phantom (100) is provided with a sunken recess (110) at a middle position of an upper surface thereof and with several conical holes on a side surface thereof. The sunken recess (110) is fixedly connected with a two dimensional ultrasound probe (220) therein. The conical hole is inserted with an NDI insertion stylus (230), and a tip of the NDI insertion stylus (230) can be acquired in ultrasound imaging. An ultrasound probe calibration system employing the above structure enables a midplane of an ultrasound plane to pass a midplane of an ultrasound probe calibration phantom (100) along a middle gap, such that a tip of an NDI insertion stylus (230) is used for the midplane of the ultrasound plane, thereby addressing the problem of misalignment of a point-type phantom or a two-dimensional plane-type phantom to the ultrasound plane.

  • Publication number: 20190073752
    Abstract: The application relates to a method and device for removing a scanning bed from a CT image. The method includes steps: reading a three-dimensional CT image, counting an amount of kernels in a CT apparatus and initializing sub-algorithms through a main thread of an image processing apparatus; extracting two-dimensional scanning images from the input three-dimensional CT image, automatically allocating the two-dimensional scanning images to kernels through the main thread of the image processing apparatus by sharing a memory, thereby realizing a multi-thread parallel processing to perform a bed removing operation on the two-dimensional scanning images; and ending the parallel processing and outputting a three-dimensional CT image without scanning bed information through the image processing apparatus. The method of the disclosure is very effective and accurate.
