  • Publication number: 20230290275
    Abstract: A system comprises a user control system including an input control device for controlling motion of a virtual medical instrument through a virtual passageway. The system further comprises a display for displaying a graphical user interface and a plurality of training modules. The graphical user interface includes a representation of the virtual medical instrument and a representation of the virtual passageway. The system further comprises a non-transitory, computer-readable storage medium that stores a plurality of instructions executable by one or more computer processors. The instructions for performing operations comprise navigating the virtual medical instrument through the virtual passageway based on commands received from the user control system and evaluating one or more performance metrics for tracking the navigation of the virtual medical instrument through the virtual passageway.

  • Publication number: 20230091099
    Abstract: A medical system comprises a display system and a medical instrument. The system further comprises a control system communicatively coupled to the display system. The control is system configured to display image data of a patient anatomy via the display system. The control system is further configured to determine, while the medical instrument navigates the patient anatomy, that a distal portion of the medical instrument is within a threshold distance of a target location in the patient anatomy. The control system is further configured to display an anatomical boundary via the display system if the distal portion of the medical instrument is within the threshold distance of the target location, the anatomical boundary indicating a surface of an anatomical structure of the patient anatomy.

  • Publication number: 20230034112
    Abstract: A medical system comprises a display system, a user input device, and a control system communicatively coupled to the display system and the user input device. The control system is configured to display image data of an anatomical region via the display system, determine a target location in the anatomical region, and determine an anatomical boundary based on the target location. The anatomical boundary indicates a surface of an anatomical structure in the anatomical region. The control system is further configured to determine a trajectory zone around a path between an exit point and the target location. The control system is further configured to determine a zone boundary based on an intersection of the trajectory zone with the anatomical boundary.

  • Patent number: 11087549
    Abstract: Systems, methods, apparatuses, and computer program products for creating freely explorable, dynamic and photorealistic virtual environments, reconstructing view dependent holograms in real-time, and inserting 3D virtual objects into 360 camera based navigable environment. A method, may include simultaneously capturing 360 video data and audio data from a plurality of viewpoints within a real-world environment. The method may also include preprocessing and compressing the 360 video data and the audio data into a three-dimensional representation suitable for display. The method may further include rendering a virtual environment of the real-world environment. In addition, the method may include creating a blended virtual environment by combining the captured 360 video data and the audio data with the rendered virtual environment. Further, the method may include displaying the blended virtual environment in a display apparatus of a user.

  • Patent number: 10339663
    Abstract: Systems and methods are disclosed for generating georeference information with respect to aerial images. In particular, in one or more embodiments, systems and methods generate georeference information relating to aerial images captured without ground control points based on existing aerial images. For example, systems and methods can access a new set of aerial images without ground control points and utilize existing aerial images containing ground control points to generate a georeferenced representation corresponding to the features of the new set of aerial images. Similarly, systems and methods can access a new image without ground control points and utilize an existing georeferenced orthomap to produce a georeferenced orthomap corresponding to the features of the new image. One or more embodiments of the disclosed systems and methods permit users to obtain georeference information related to new images without the need to place ground control points or collect additional georeference information.
