Abstract
A method for visualization guidance of device-to-image registration includes acquiring image data of a patient, generating a 3D model of the anatomy of the patient based on the image data, performing initial registration between image space and device space, advancing a device into a structure, tracking trajectory of the device in relation to the model, determining divergence between the device trajectory and the model, and effecting correction to the model or the device trajectory to minimize the divergence.
