摘要： A method includes receiving anatomic image data comprising a plurality of graphical units; generating an initial segmented set of the plurality of graphical units associated with an anatomic tree structure; receiving an indication of a first user selected graphical unit, the first user selected graphical unit being outside the initial segmented set of the plurality of graphical units; applying a cost function to determine a first sequence of graphical units from the first user selected graphical unit to the initial segmented set of graphical units; receiving an indication of a second user selected graphical unit, the second user selected graphical unit being selected from the first sequence of the plurality of graphical units; and applying the cost function to determine a second sequence of the plurality of graphical units from the second user selected graphical unit to the initial segmented set of the plurality of graphical units.

摘要： 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.

摘要： A method of building an anatomical branch model comprises receiving anatomical image data comprising a plurality of graphical units associated with an anatomical structure and determining a plurality of parent segments and child segments. The method also comprises determining a set of relationships between the parent segments and the child segments by determining a first set of connection costs of connecting at least one of the parent segments to a first subset of the child segments, the child segments of the first subset are separated from the at least one of the parent segments by one or more gaps, identifying a first child segment from the first subset of the child segments based on a first connection cost, and connecting the first child segment to the at least one parent segment. The method further comprising generating an image of the anatomical branch model based on the determined set of relationships.

摘要： A method of building an anatomical branch model comprises receiving anatomical image data comprising a plurality of graphical units associated with an anatomical structure and determining a plurality of parent segments and child segments to include a plurality of linked graphical units from the plurality of graphical units. The method also comprises determining a set of relationships between the parent segments and the child segments and generating an image of the anatomical branch model based on the determined set of relationships between the parent segments and the child segments.
