Endoscope Patents (Class 348/45)
  • Patent number: 10321803
    Abstract: Systems and methods for endoscopic procedures employ a first technique to ensure initial correct alignment of an endoscope (100) with a desired target (10). A reference image (51) is then acquired from an imaging arrangement associated with the endoscope. During a subsequent stage of the procedure, tracking of the endoscope position relative to the target is performed partially or entirely by image-based tracking by comparing features in real-time video image (52) produced by imaging arrangement with features in the reference image (51). The feature comparison may be performed visually by a user, or may be automated to offer more specific corrective suggestions to the user.

  • Patent number: 10288803
    Abstract: An image-conducting optical fiber bundle extends along a central bundle axis between image input and image output ends. The bundle is twisted along a portion of its length such that an image inputted into the image input end is angularly displaced about the central bundle axis before being outputted through the image output end. Each constituent optical fiber includes a cladding with a cladding diameter corresponding with the fiber diameter of that fiber and a core with a core diameter. The ratio of the core diameter to the cladding diameter defines a core-to-clad diameter ratio relative to each fiber. In various embodiments, at least one of fiber diameter and core-to-clad diameter ratio varies as a function of a fiber's radial displacement from the central bundle axis.

    Abstract: A monitoring system tracks the non-visible structure of a body in three dimensions. A tracker obtains image information of the object and instruments in its vicinity, all bearing 3D tracking markers with at least one pattern segment. A controller spatially relates image information with previously obtained scan data of the object revealing non-visible structure of the object. For the scan a fiducial reference detectable in the scan is removably attached to a location on the object. Scan data and image information is used by the controller to provide the user with real time information on relative 3D locations and orientations of instruments and the non-visible structure of the body. The monitoring system may be used to model and track changes in the body itself. A model of the body and instruments is used to track contemplated actions and warn about possibly inappropriate instrument procedures.

  • Patent number: 9625995
    Abstract: The technology disclosed relates to identifying an object in a field of view of a camera. In particular, it relates to identifying a display in the field of view of the camera. This is achieved by monitoring a space including acquiring a series of image frames of the space using the camera and detecting one or more light sources in the series of image frames. Further, one or more frequencies of periodic intensity or brightness variations, also referred to as ‘refresh rate’, of light emitted from the light sources is measured. Based on the one or more frequencies of periodic intensity variations of light emitted from the light sources, at least one display that includes the light sources is identified.

  • Patent number: 9595128
    Abstract: A method and apparatus for rendering of image data for a multi-view display, such as image data for a lenticular auto-stereoscopic display, is disclosed. The method comprises the steps of receiving an image signal representing a first image, the first image comprising 3D image data, and spatially filtering the first image signal to provide a second image signal. The second image signal represents a second image, the spatial filtering being, e.g., a low-pass filter, a high-pass filter or a combination of a low-pass and a high-pass filter. A strength of the spatial filter is determined by a reference depth of the first image and a depth of an image element of the first image. The second image is sampled to a plurality of sub-images, each sub-image being associated with a view direction of the image.

  • Patent number: 9544533
    Abstract: Systems and apparatus may include converter device(s), a matrix switch, processor(s), and memory(s), where one or more of the converter devices provide video input signals to the matrix switch. A processor may determine if one of a plurality of video signals input to the matrix switch includes data representative of identification information overlain on a video image derived from one of the plurality of video signals. The determination may be based on a flag value stored in the converter device(s). The flag value may be retrieved by a server coupled to the matrix switch. If the information is included in the video signal, the video signal may be passed through a path in a matrix switch configured by the processor. If the information is not included in the video signal, the data representative of identification information may be retrieved from the converter device and then overlain on the video image.
