Abstract:
Anatomical feature tracking involves advancing a medical instrument to a treatment site of a patient, the medical instrument comprising an imaging device, generating a first image of at least a portion of the treatment site using the imaging device of the medical instrument when a distal end of the medical instrument is in a first position, generating a first silhouette of a first target anatomical feature represented in the first image, generating a second image of at least a portion of the treatment site using the imaging device of the medical instrument when the distal end of the medical instrument is in a second position, generating a second silhouette of a second target anatomical feature represented in the second image, and determining a target position at the treatment site based at least in part on the first silhouette and the second silhouette.
