Abstract
A method performed by a computing system comprises receiving a fluoroscopic image of a patient anatomy while a portion of a medical instrument is positioned within the patient anatomy. The fluoroscopic image has a fluoroscopic frame of reference. The portion has a sensed position and sensed orientation in an anatomic model frame of reference. The method further comprises identifying the portion in the fluoroscopic image and identifying an extracted position and an extracted orientation of the portion in the fluoroscopic frame of reference using the identified portion in the fluoroscopic image. The method further comprises registering the fluoroscopic frame of reference to the anatomic model frame of reference based on the sensed position of the portion, the extracted position of the portion, the sensed orientation of the portion, and the extracted orientation of the portion.
