Abstract
Systems, methods and devices are disclosed for use in electronic guidance systems for surgical navigation. A sensor is provided with an optical sensor and an inclinometer (e.g. accelerometer or other inclination measuring sensor) and communicates measurements of patient inclination to an inter-operative computing unit. The computing unit is configured to determine patient movement (e.g. relative to an initial patient position) and provide inclination measurements graphically via a GUI to represent patient movement during a procedure. The graphic may be selectively displayed. In one example, a bubble level graphic is displayed to indicate patient movement. A direction of the bubble level may utilize a registration coordinate frame of the patient and the current inclination expressed with respect to the anatomical directions of the patient.
