  • Patent number: 10188467
    Abstract: A system and method for providing image guidance for placement of one or more medical devices at a target location. The system can determine one or more intersections between a medical device and an image region based at least in part on first emplacement data and second emplacement data. Using the determined intersections, the system can cause one or more displays to display perspective views of image guidance cues, including an intersection indicator in a virtual 3D space.

  • Patent number: 10127629
    Abstract: A system and method of providing composite real-time dynamic imagery of a medical procedure site from multiple modalities which continuously and immediately depicts the current state and condition of the medical procedure site synchronously with respect to each modality and without undue latency is disclosed. The composite real-time dynamic imagery may be provided by spatially registering multiple real-time dynamic video streams from the multiple modalities to each other. Spatially registering the multiple real-time dynamic video streams to each other may provide a continuous and immediate depiction of the medical procedure site with an unobstructed and detailed view of a region of interest at the medical procedure site at multiple depths. A user may thereby view a single, accurate, and current composite real-time dynamic imagery of a region of interest at the medical procedure site as the user performs a medical procedure.

  • Patent number: 9538167
    Abstract: Methods, systems, and computer readable media for shader lamps-based avatars of real and virtual people are disclosed. According to one method, shader lamps-based avatars of real and virtual objects are displayed on physical target objects. The method includes obtaining visual information of a source object and generating at least a first data set of pixels representing a texture image of the source object. At least one of a size, shape, position, and orientation of a 3D physical target object are determined. A set of coordinate data associated with various locations on the surface of the target object are also determined. The visual information is mapped to the physical target object. Mapping includes defining a relationship between the first and second sets of data, wherein each element of the first set is related to each element of the second set.
