  • Patent number: 10303264
    Abstract: An optical encoder has a displacement generating unit, a light-emitting unit and an optical navigation integrated circuit. The displacement generating unit has an axle body movable along a central axial line thereof. The axle body has a free end with a diameter larger than a part of the axle body and a planar working surface formed on the free end. The light-emitting unit is configured for operatively providing a light beam to irradiate the working surface of the displacement generating unit. The light beam has a divergence angle within a range to reduce scattering. The optical navigation integrated circuit receives the reflected light beam reflected by the working surface, and calculates a relative displacement between the optical navigation integrated circuit and the working surface.

  • Patent number: 10262424
    Abstract: An embodiment in accordance with the present invention provides a method for 3D-2D registration (for example, registration of a 3D CT image to a 2D radiograph) that permits deformable motion between structures defined in the 3D image based on a series of locally rigid transformations. This invention utilizes predefined annotations in 3D images (e.g., the location of anatomical features of interest) to perform multiple locally rigid registrations that yield improved accuracy in aligning structures that have undergone deformation between the acquisition of the 3D and 2D images (e.g., a preoperative CT compared to an intraoperative radiograph). The 3D image is divided into subregions that are masked according to the annotations, and the registration is computed simultaneously for each divided region by incorporating a volumetric masking method within the 3D-2D registration process.

  • Patent number: 10217019
    Abstract: An approach is provided for correlating a comment about an image with first object(s) in the image. Object(s) in the image are detected and identified. Based on a cognitive and contextual analysis of the comment, the first object(s) included in the identified object(s) are determined to be referred to by the comment. Responsive to determining that the first object(s) are referred to by the comment, the comment is linked with the first object(s). Alternately, based on a cognitive and contextual analysis of the comment about the image, the comment is determined to be referring to object(s). Responsive to determining that the comment refers to the object(s), the image is scanned and responsive to the image being scanned, the object(s) are identified in the image. Based on the comment referring to the object(s) and responsive to the object(s) being identified, the comment is linked with the identified object(s).

  • Patent number: 10204411
    Abstract: A system and method for segmenting an image stream to a plurality of segments is provided. A processing unit may be configured to calculate a set of pixel-based properties for frames of an image stream, and detect segments of constant mean values in the sets of pixel-based properties. The segments of constant mean values are detected by using a window method that determines possible partition points of the window, and calculating a difference between mean values of the sets of pixel-based properties for each sub-window of frames. Points of change may be identified in the calculated difference between mean values of the sets of pixel-based properties. A display unit may display a summarized representation of the image stream, wherein the summarized representation includes a plurality of segments, each segment corresponding to a segment of constant mean values in the sets of pixel-based properties.

  • Patent number: 10169865
    Abstract: An x-ray imaging system data acquisition and image reconstruction system and method are disclosed which enable optimizing the image parameters based on multiple tomographic volumes of the sample that have been captured using an x-ray microscopy system. This enables the operator to control the image contrast, for example, of selected slices, and apply the information associated with optimizing the contrast of the selected slice to all slices in two or more tomographic volume data sets. This creates a combined volume with optimized image contrast throughout. Also, the system enables navigation within the volumes through functional annotation, improvements in volume registration and improvements in noise suppression both within the volumes and within slice histograms of the sample.
