  • Patent number: 11071508
    Abstract: When X-ray CT imaging is performed with a part located close to a front of a head as the imaging region, using the turning mechanism and the distance changing mechanism, the turning controller causes the X-ray generator and the X-ray detector to turn around the head while locating the imaging region therebetween, and causes the X-ray detector to turn along a go-around orbit, in which the X-ray detector comes close to the imaging region with respect to a front side of the head and moves away from the imaging region with respect to a rear side, by changing a distance between the X-ray detector and the center of the imaging region.

  • Patent number: 11041820
    Abstract: The present invention relates to a magnetic holder for immunoelectron microscopy grids. The holder comprises a frame, a magnet and a hydrophobic layer. The device can use a magnetic force to simultaneously attach the outer rings of nickel grids to the frame, so that a batch operation (such as rinsing, immunolabeling and dyeing) of the nickel grids can be realized. In addition, due to the hydrophobic effect of the hydrophobic layer, the holder can reduce the amount of the liquid carried by the nickel grids in the process of continuously transferring the nickel grids between different types of liquids to almost zero. Compared with the prior art, the magnetic holder effectively reduces the probability of cross-contamination between reagents.
