摘要： A method comprises receiving a set of model points of a model of one or more passageways of a patient. The method further comprises receiving a set of measured points collected from within the one or more passageways of the patient. Each point comprises coordinates within a medical environment occupied by the patient. The method further comprises matching each measured point to a model point to generate a set of matches. The method further comprises assigning a weight to each of the measured points based on the set of matches to generate a weighted set of matches. The method further comprises moving the set of measured points relative to the set of model points based on the weighted set of matches.

摘要： 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.

摘要： Information extracted from sequential images captured from the perspective of a distal end of a medical device moving through an anatomical structure are compared with corresponding information extracted from a computer model of the anatomical structure. A most likely match between the information extracted from the sequential images and the corresponding information extracted from the computer model is then determined using probabilities associated with a set of potential matches so as to register the computer model of the anatomical structure to the medical device and thereby determine the lumen of the anatomical structure which the medical device is currently in. Sensor information may be used to limit the set of potential matches. Feature attributes associated with the sequence of images and the set of potential matches may be quantitatively compared as part of the determination of the most likely match.

摘要： A method of registering sets of anatomical data for use during a surgical procedure is provided herein. The method may include segmenting a set of first modality image data representing a model of one or more passageways within a patient and generating a first set of points based on the segmented set of first modality image data representing the model of the one or more passageways. The method may further include determining a set of matches between a second set of points and the first set of points, wherein the second set of points is obtained by a second modality and discarding a subset of the set of matches based on a first heuristic to generate a modified set of matches. The second set of points may then be moved relative to the first set of points based on the modified set of matches.

摘要： A non-transitory machine-readable media storing instructions is provided. The instructions cause one or more processors to: define a subregion of a model of an anatomic region of a patient anatomy, the subregion corresponding to an area surrounding a tip of an image capture probe located within the anatomic region, the subregion including a plurality of virtual tissue structures—a set of virtual tissue structures of the plurality of virtual tissue structures is situated distally from the tip of the probe; compare a tissue structure in an image received from a camera positioned at the tip of the probe to a portion of the plurality of virtual tissue structures to identify a closest matched virtual tissue structure; and based on identification of the closest matched virtual tissue structure, register the image to the model to identify a virtual probe position for the tip of the probe with respect to the model.

摘要： A device comprises an instrument usable to collect location data for one or more passageways. The device further comprises one or more processors coupled to the instrument. The one or more processors are configured to organize a plurality of points within the location data by clustering the plurality of points based on distances between points of the plurality of points. The processor(s) are further configured to create a passageway tree based on the organized points and to identify at least three non-collinear landmark locations within the passageway tree. The processor(s) are further configured to create a seed transformation between one or more of the at least three non-collinear landmark locations and corresponding model locations in model data. The processor(s) are further configured to register, using the seed transformation, the plurality of points to the model data for the one or more passageways.

摘要： A computer-assisted medical device is configured and used to endoluminally navigate to a location in the gastrointestinal system and there treat certain body lumen wall areas while avoiding other body lumen wall areas. Embodiments ablate the inner mucosal layer and sub-mucosal nerve plexus of the stomach, duodenum and jejunum to effect treatment of insulin resistance and metabolic disorders, such as Type II diabetes (T2D), polycystic ovarian syndrome (PCOS), non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD), congestive heart failure (CHF) and obstructive sleep apnea (OSA). Various sensors are used to assist a clinical operator to navigate from the mouth through the pyloric sphincter and into and through the duodenum and/or jejunum. Various sensors are used to map and identify portions of the duodenum and/or jejunum. Various lumen wall ablation devices and methods are described. Various post-treatment assessments are described.
