APPARATUS AND METHOD FOR CHARACTERIZATION OF ACUTE OTITIS MEDIA

Abstract: an ultrasound signal processor uses an excitation generator to cause displacement of a tympanic membrane while a series of ultrasound pulses are applied to the tympanic membrane. phase differences between a transmitted signal and received signal are examined to determine the movement of the tympanic membrane in response to the applied excitation. an examination of the phase response of the tympanic membrane provides a determination as to whether the fluid type behind the tympanic membrane is one of: no fluid, serum fluid, or purulent fluid.
