Abstract: Systems and methods track objects within an operating room. A machine vision system includes at least one camera and a machine vision controller. A navigation system includes a camera unit including a plurality of sensor arrays. The sensor arrays include a plurality of sensing elements. For each of the plurality of sensor arrays, the navigation system identifies a first subset of the plurality of sensing elements to be active based on the position of the object and a second subset of the plurality of sensing elements to be inactive based on the position of the object. The navigation processor 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.

Abstract: A camera unit for use with a surgical navigation system. The camera unit includes an outer casing and a rigid support structure enclosed within the outer casing. Two first optical sensors are coupled to the outer casing, and each including sensing elements adapted to sense light in a near-infrared spectrum. The two first optical sensors are commonly fixed to the rigid support structure and are separated by a predefined distance on the rigid support structure so as to be stereoscopically arranged. A second optical sensor is coupled to the outer casing and is adapted to sense light in a visible light spectrum. A camera controller is disposed within the outer casing and is configured to control the two first optical sensors and the second optical sensor for tracking an object within an operating room.

Abstract: Surgical navigation systems and methods for tracking an object within an operating room involve a camera unit that houses a first stereoscopic sensing system and a second stereoscopic sensing system each comprising sensing elements adapted to sense light. A controller utilizes the first stereoscopic sensing system to sense light from the object and track the object according to a first resolution. The controller utilizes the second stereoscopic sensing system to sense light from the object and track the object according to a second resolution that is lower than the first resolution. The controller obtains data related to the object from the second stereoscopic sensing system and modifies control of the sensing elements of the first stereoscopic sensing system based on the obtained data related to the object.

Abstract: Systems, methods and software are provided for aiding in positioning of a camera relative to objects in a surgical environment. The camera has a 3D field of view and senses positions of the objects in the field of view. A controller is coupled to the camera and defines a first zone and a second zone within the field of view. Each zone defines a range of acceptable positions for one of the objects relative to a position of the camera. The controller receives the position of the objects. A graphical user interface displays image representations of: the field of view, the first zone relative to the field of view, the second zone relative to the field of view, the position of one object relative to the first zone, and the position of another object relative to the second zone.
