Methods may be provided to operate an image-guided surgical system using imaging information for a 3-dimensional anatomical volume. A trigger can be detected based on information received from a tracking system regarding a probe. A pose of the probe can be detected based on the information received from the tracking system. A location in the 3-dimensional anatomical volume can be identified based on the pose of the probe and based on the imaging information. The location can be stored in memory based on detecting the trigger and detecting the pose of the probe.
