摘要： The present invention is disclosing several methods related to intra-body navigation of radiopaque instrument through natural body cavities. One of the methods is disclosing the pose estimation of the imaging device using multiple images of radiopaque instrument acquired in the different poses of imaging device and previously acquired imaging. The other method allows to resolve the radiopaque instrument localization ambiguity using several approaches, such as radiopaque markers and instrument trajectory tracking.

摘要： A device including a sheath having a proximal end, a distal end, and a lumen extending through the sheath from the proximal end to the distal end, wherein the sheath is biased to a released position; a pull wire extending along the sheath and being coupled to the sheath at the distal end, wherein the pull wire and the sheath are configured to cooperate such that pulling the pull wire toward the proximal end causes the distal end to assume an active position, and such that release of the pull wire causes the distal end to return to the released position; and a control portion coupled to the proximal end of the sheath and to the pull wire, wherein the control portion includes a control element operable to selectively pull the pull wire toward the proximal end of the sheath or to release the pull wire.

摘要： A method includes receiving a sequence of medical images captured by a medical imaging device while the medical imaging device travels through a rotation, and showing an area of interest including a plurality of landmarks; determining a pose of each of a subset of the sequence of medical images in which the landmarks are visible; estimating a trajectory of the medical imaging device based on the determined poses of the subset and a trajectory constraint of the imaging device; determining a pose of one of the medical images in which the landmarks are not visible by extrapolating based on an assumption of continuity of movement of the medical imaging device; and determining a volumetric reconstruction for the area of interest based at least on at least some of the poses of the subset and the pose of the one of the medical images in which the landmarks are not visible.
