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.

Abstract: Methods of positioning a surgical instrument can involve advancing a first medical instrument to a treatment site of a patient, the first medical instrument comprising a camera, recording a target position associated with a target anatomical feature at the treatment site, generating a first image of the treatment site using the camera of the first medical instrument, identifying the target anatomical feature in the first image using a pretrained neural network, and adjusting the target position based at least in part on a position of the identified target anatomical feature in the first image.
