  • ULTRASONIC DETECTION OF EAR DISORDERS
    Publication number: 20100069752
    Abstract: An apparatus and method for determining ear fluid viscosity. A transducer is operable to transceive a signal to interact with a fluid-containing portion of the ear. The viscosity of the fluid is determined using the transceived signal.
    Type: Application
    Filed: November 23, 2009
    Publication date: March 18, 2010
    Applicant: OTOSONICS, INC.
    Inventors: Jan Lewandowski, Robert A. Bessler

  • Characterization of middle ear effusion
    Publication number: 20040167404
    Abstract: A method for the detection and characterization of fluid behind the tympanic membrane. More specifically, a method for differentiating between infective and non infective effusions behind the tympanic membrane in animals, particularly humans, and more particularly, human children, based on analysis of the rheological properties of the fluid using an ultrasonic source.
