Abstract

A medical tracking system includes a reference device including a sensor docking feature configured to mate with a mating portion of a sensor device. The sensor docking features hold the mating parts in a known configuration. The fiducial device also includes at least one imageable fiducial marker and a surface configured for attachment to the patient's anatomy.

Description

technical field [0001] The present disclosure relates to systems and methods for navigating patient anatomy for minimally invasive procedures, and more particularly to systems and methods for tracking interventional instruments using shape sensor systems. Background technique [0002] Minimally invasive medical techniques are intended to reduce the amount of tissue damaged during interventional procedures, thereby reducing patient recovery time, discomfort, and unwanted side effects. Such minimally invasive techniques may be performed through natural orifices in the patient's anatomy or through one or more surgical incisions. Through these natural orifices or incisions, clinicians insert interventional instruments, including surgical, diagnostic, therapeutic, or tissue examination instruments, to reach target tissue sites. Minimally invasive interventional devices navigate natural or surgically created conduits in anatomical systems such as the lungs, colon, intestines, kid...
