Abstract
Systems and methods track objects within an operating room. A machine vision system includes a camera and a controller. A navigation system includes a camera unit including a sensor array. The sensor array includes a plurality of sensing elements. The controller system identifies a first subset of the plurality of sensing elements to be active based on the position of the object. The controller is also configured to track a movement of the object within the operating room using the first subset of the plurality of sensing elements while preventing the use of the second subset of the plurality of sensing elements.
Claims22
A navigation system for tracking an object within an operating room, the navigation system comprising:
- an optical sensor, the optical sensor comprising a plurality of sensing elements;
- and
- a controller in communication with the optical sensor;
- wherein the controller is configured to:
- store data indicative of a position of the object within an operating room;
- operate a first subset of the plurality of sensing elements based on the position of the object, the first subset being less than all of the sensing elements comprising the plurality of sensing elements;
- and
- track a movement of the object within the operating room using the first subset of the plurality of sensing elements.
A navigation system for tracking an object within an operating room, the navigation system comprising:
- a first optical sensor, the first optical sensor comprising a first plurality of sensing elements and having a first field of view;
- a second optical sensor, the second optical sensor comprising a second plurality of sensing elements and having a second field of view;
- and
- a controller in communication with the first optical sensor and the second optical sensor;
- wherein the controller is configured to:
- store data indicative of a position of the object within an operating room;
- operate a first subset of the first plurality of sensing elements based on the position of the object at a first time;
- operate a second subset of the second plurality of sensing elements based on the position of the object at a second time, the second time being different from the first time;
- and
- track a first movement of the object within the operating room using the first subset of the first plurality of sensing elements at the first time and track a second movement of the object within the operating room using the second subset of the second plurality of sensing elements at the second time.
A method of tracking an object within an operating room with a navigation system including a camera unit including an optical sensor, a controller in communication with the optical sensor, wherein the optical sensor includes a plurality of sensing elements, the method comprising:
- determining a position of the object within an operating room using the navigation system;
- storing, with the controller, data indicative of the position of the object;
- operating, with the controller, a first subset of the plurality of sensing elements based on the position of the object, the first subset being less than all sensing elements comprising the plurality of sensing elements;
- and
- tracking, with the controller, a movement of the object within the operating room using the first subset of the plurality of sensing elements.
