Abstract: Certain aspects relate to systems and techniques for navigation path tracing. In one aspect, a system displays a preoperative model of a luminal network is displayed. The system determines a position of an instrument within the luminal network relative to the preoperative model. Based on the position of the instrument relative to the preoperative model, the system determines whether to enter a path tracing mode. In path tracing mode the system displays visual indicia indicative of a path of the instrument with respect to the displayed preoperative model. The visual indicia may be used to visual the navigation path of the instrument and/or to extend the preoperative model.

Abstract: Image co-registration entails: emitting energy, and responsively and dynamically acquiring images, the acquired images having a given dimensionality; selecting, repeatedly, and dynamically with the acquiring, from among the acquired images and, as a result of the selecting, changing, repeatedly, and dynamically, membership in a set of images of the given dimensionality; and, synchronously with the change, dynamically and iteratively registering the set to an image having a dimensionality higher than the given dimensionality. The co-registration is realizable with an imaging probe for the acquiring, and a tracking system for tracking a location, and orientation, of the probe, the registering being specialized for the acquiring with the probe being dynamically, during the acquiring, any one or more of angulated, rotated and translated.
