  • Publication number: 20230242250
    Abstract: A computer stores dense maps generated by one or more aerial vehicles. The computer generates a global graph based on the dense maps and a sparse map. The computer stores a representation of one or more paths traversed by the one or more aerial vehicles within the global graph. The computer determines a path from an origin location to a destination location based on the global graph. The determined path enables an aerial vehicle to avoid objects.

  • 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: 20230088056
    Abstract: Medical imaging systems and methods are provided herein that provide for navigation and procedure planning without segmentation. A method comprises receiving, by a medical imaging system having at least: one processing device, three-dimensional image data of a patient anatomy. The method also comprises filtering the three-dimensional data to display a portion of the three-dimensional image data that is associated with the patient anatomy and receiving, at the processing device, input from an operator input device. The input comprises navigational directions for virtual movement within a space defined by the three-dimensional image data. The method also includes tracking the virtual movement and generating a first model of the patient anatomy based on the tracked virtual movement.

  • 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.

  • Publication number: 20220254104
    Abstract: An exemplary processing system accesses a three-dimensional (3D) model of an anatomical structure of a patient and applies a detection process to the 3D model to detect a single-layer anatomical feature in the anatomical structure. The detection process includes generating, from the 3D model, a probability map of candidate points for the single-layer anatomical feature, and generating, based on the probability map of candidate points, a single-layer mesh representing the single-layer anatomical feature.

  • Publication number: 20210401508
    Abstract: A medical system may comprise a display system, a user input device, a medical instrument, and a manipulator assembly configured to support and operate the medical instrument. The medical system may also comprise a control system. The control system may be configured to display image data corresponding to a three-dimensional anatomical region via the display system, receive a first user input to generate a first curve in the three-dimensional anatomical region via the user input device, and receive a second user input to generate a second curve in the three-dimensional anatomical region via the user input device. The control system may also be configured to determine an anatomical boundary bounded by the first curve and the second curve. The control system may also be configured to control the manipulator assembly to operate medical instrument using the determined anatomical boundary to limit movement of the medical instrument.
