Registration and navigation using a three-dimensional tracking sensor

摘要

Systems and methods for registration and navigation using a 3D tracking sensor are shown and described. The systems and methods utilize a 3D tracking sensor coupled to a portable surgical element to track a trackable element fixed to an object. The pose of the trackable element is determined based at least in part on information provided by the 3D tracking sensor, and the object is registered to a three-dimensional representation of the object. The 3D tracking sensor can also be used to track various objects during a surgical procedure.

1. A surgical system, comprising:
a 3D tracking sensor coupled to a portable surgical element; a trackable element fixed to an object; a surgical controller configured to:
determine a pose of the trackable element based at least in part on information provided by the 3D tracking sensor; andregister the object to a three-dimensional representation of the object; wherein the 3D tracking sensor is configured to obtain three-dimensional information related to the trackable element by capturing at least a first image and a second image of the trackable element; and wherein the surgical controller determines the pose of the trackable element at least in part by comparing the image intensities of the first and second images.
