摘要： Systems and methods for supporting image-guided procedures include an elongate device including a steerable distal end and a shape sensor located along a length of the elongate device and one or more processors coupled to the elongate device. While the elongate device is being traversed through one or more passageways of a patient, the one or more processors are configured to detect a data collection event, and capture, in response to detecting the data collection event, a plurality of points along the length of the elongate device using the shape sensor. In some embodiments, an insertion depth of the elongate device is monitored. In some embodiments, the data collection event is detected when the insertion depth is beyond a threshold insertion depth, no change of the insertion depth is detected for longer than a threshold period of time, or the insertion depth is beyond a threshold retraction distance.

摘要： A system comprises a medical instrument including a sensing tool and comprises a processing unit including one or more processors. The processing unit is configured to receive data related to a patient anatomy from the sensing tool while the medical instrument traverses the patient anatomy. The processing unit is further configured to construct an anatomic model of the patient anatomy from the data received from the sensing tool. The processing unit is further configured to generate an image of the anatomic model for display and register a position of the medical instrument to the anatomic model.

摘要： A method for modeling a patient anatomy includes applying a first modeling function to a set of volumetric image data for a patient anatomy to produce a first model of the patient anatomy, presenting the first model to a user, receiving an input from the user, and generating a revised model based upon the input.

摘要： An apparatus is configured to show telestration in 3-D to a surgeon in real time. A proctor is shown one side of a stereo image pair, such that the proctor can draw a telestration line on the one side with an input device. Points of interest are identified for matching to the other side of the stereo image pair. In response to the identified points of interest, regions and features are identified and used to match the points of interest to the other side. Regions can be used to match the points of interest. Features of the first image can be matched to the second image and used to match the points of interest to the second image, for example when the confidence scores for the regions are below a threshold value. Constraints can be used to evaluate the matched points of interest, for example by excluding bad points.
