  • Patent number: 10925678
    Abstract: Provided is an optical tracking tool for navigating a surgery, comprising a mounting base. The mounting base is provided with two to six supporting faces thereon. Two or four reflective balls are arranged on each of the supporting faces. A positioning surface is formed by the four reflective balls located on the same supporting face or the four reflective balls respectively located on two adjacent supporting faces. An included angle between surface normal vectors of two adjacent positioning surfaces is 90°-140°. As compared with a tracking tool having a single positioning surface formed by four reflective balls in the prior art, the optical tracking tool can considerably broaden an effective tracking range of a system, thereby improving system accuracy.

  • Publication number: 20210005334
    Abstract: An elongate fuel element is described that has a silicon carbide cladding enclosing a fuel, such as UO2, wherein the fuel is dimensioned relative to the cladding to define gaps at each lateral end of the enclosure sufficiently large such that upon swelling in use, the fuel does not increase the strain on the cladding beyond the limits of the claddings strain tolerance. The lateral gaps at the ends of the fuel allow lateral expansion during swelling that reduces the strain on the cladding.

  • Publication number: 20200363337
    Abstract: Disclosed are a low-fluorescence-photobleaching confocal imaging method and system. A confocal image is first selected as a reference image, and a threshold is set based on pixel values of the reference image. Then the density of fluorescent molecules in a pixel is determined based on a result of comparison of a real-time fluorescence intensity feedback and the threshold. Finally, an illumination time for the pixel is controlled based on the density of fluorescent molecules in the pixel to obtain a low-fluorescence-photobleaching confocal imaging image. The low-fluorescence-photobleaching confocal imaging method and system provided herein control the illumination time for each object-side pixel to make more efficient use of fluorescence information and reduce fluorescence photobleaching without sacrificing image quality, and so can be applied to a variety of biological samples. Further provided is a low-fluorescence-photobleaching confocal imaging system.
