Method and system of measuring patient position

Abstract:

A method of measuring patient position by a patient monitoring system includes providing a first position sensor attachable to a portion of the patient, and providing a hub device that includes a calibration position sensor. A first calibration position measurement is received from the calibration position sensor while the hub device is aligned with the portion of the patient where the first position sensor is attached. A first patient position measurement is received from the first position sensor, and then a calibration map is determined for the first position sensor based on a difference between the first calibration position measurement and the first patient position measurement. Position measurement data is then received from the first position sensor, and a patient position is determined based on the position measurement data and the calibration map.
