Abstract: Systems and methods for tracking movement of a catheter within airways of a lung. A deformable model of the lung represents airways of the lung as airway segments joined at bifurcations. Deformation of the lung model uses modification of the angles and/or positions of the airway segments with respect to each other. An initial model may be generated, for example, based on segmentation of a CT image. A baseline deformable registration of the initial model to a lung shape of the patient at the beginning of the procedure may be established from position measurements of the catheter along plurality of different pathways. Optionally, the baseline registration is dynamic according to respiratory phase. Relative to the baseline registration, real-time changes in lung shape may be modeled by using further measurements obtained using the catheter as it navigates to a target, preferably using position sensors distributed along the catheter body.

Abstract: Flexible, longitudinally extended sensors comprising variably resistive and/or inductive sensing material. Sensors connect to an external processing unit using as few as 2 wires. In operation, sensors measure resistance/inductance along their longitudinal extent (curve). Spectral de-multiplexing allows electrical property differences along sensors to be resolved. This enables shape tracking of the flexible sensor. The sensor principles are suitable for the production of ultra-small diameter probes (for example, smaller than 0.5 mm) of arbitrary length (for example, 30 cm long). There are potential advantages for cost efficiency and ease of manufacture. The sensor can be constructed as a shape tracked guidewire to enable endovascular navigation procedures. The sensor's tracked shape enables deformation tracking of the anatomy. Using the sensor's tracked shape rather than repetitive X-ray imaging improves navigational accuracy and reduces exposure to radiation.

False-positive catheter tip candidates are removed by reconstructing a 3D position of the catheter tip and finding an intersecting point of rays corresponding to each 2D frame.
