  • Publication number: 20200245975
    Abstract: An ultrasound signal processor uses an excitation generator to cause displacement of a membrane or surface while a series of ultrasound pulses are applied to the membrane or surface. Phase differences between a transmitted signal and received signal are examined to determine the movement of the membrane or surface in response to the applied excitation. An examination of the phase response of the membrane or surface provides a determination as to whether the fluid type behind the membrane or surface is one of: no fluid, serum fluid, or purulent fluid.

  • Publication number: 20200107813
    Abstract: A device for measuring reflected ultrasound and optical signals may include: an optical source; an optical assembly comprising at least one lens, configured to focus reflected optical illumination from a target onto a detector; and an ultrasound transducer aligned to transmit and receive ultrasound radiation co-axially with the reflected optical illumination and wherein the ultrasound transducer at least partially obstructs a path of the reflected optical illumination. An obstruction may be distant from a focal spot of the optical assembly. The device for measuring reflected ultrasound and optical signals may be particularly useful for characterizing fluid behind an ear drum to diagnose otitis media.

  • Patent number: 10568515
    Abstract: An OCT apparatus and method for characterization of a fluid adjacent to a tympanic membrane has a low coherence source which is coupled to a splitter which has a measurement path and a reference path. The reference path is temporally modulated for length, and the combined signals from the reference path and the measurement path are applied to a detector. The detector examines the width of the response and the time variation when an optional excitation source is applied to the tympanic membrane, the width of the response and the time variation forming a metric indicating the viscosity of a fluid adjacent to the tympanic membrane being measured.

  • Publication number: 20200029820
    Abstract: An otoscope uses differential reflected response of optical energy at an absorption range and an adjacent wavelength range to determine the presence of water (where the wavelengths are water absorption wavelength and adjacent non-absorption excitation wavelengths). In another example of the invention, the otoscope utilizes OCT in combination with absorption and non-absorption range for bacteria and water.

  • Publication number: 20190365292
    Abstract: An acoustic otoscope generates volume change excitations of either a trapezoidal or sinusoidal waveforms which are coupled into a sealed ear canal using a speculum tip. The change in volume results in a pressure change, for which a pressure measurement is taken during the volume change excitation interval. In one example, a trapezoidal time-domain volume change is presented, and a pressure measurement waveform is stored, the pressure measurement waveform thereafter examined to find a change of slope point in time, after which the pressure measurement waveform is scaled to be equal to the volume change waveform at that same point in time, a difference between scaled pressure measurement and volume excitation is formed, and examined for peak value prior to the earlier determined change in slope point in time.

  • Publication number: 20140081144
    Abstract: Systems and methods for processing echo signals in a Doppler ultrasound system from a region of interest. An ultrasound beam is electronically steered to deliver ultrasound to and receive echo signals from a plurality of sample locations in the region of interest. The echo signals for each sample location are processed to extract Doppler shift signals and Doppler shift data representing the Doppler shift signals are generated. The Doppler shift data accumulated for the sample locations can be used to detect the presence of blood flow in the region of interest, and identify the location in the region of interest at which the presence of blood flow is detected. The blood flow can be tracked by updating the location of the detected blood flow in the region of interest. The blood flow can be further monitored by combining the locating and tracking functionality with an m-mode ultrasound image.

  • Patent number: 8394025
    Abstract: A method and apparatus for obtaining the absolute value of intracranial pressure in a non-invasive manner is described by using an ultrasonic Doppler measuring device which detects the intracranial and extracranial blood flow velocities of the intracranial and extracranial segments of the ophthalmic artery. The eye in which the blood flow is monitored is subjected to an external pressure, sufficient to equalize the intracranial and extracranial angle-independent blood flow factors calculated from the intracranial velocity signal and extracranial velocity signal.

The eye in which the blood flow is monitored is subjected to an external pressure, sufficient to equalize the intracranial and extracranial angle-independent blood flow factors calculated from the intracranial velocity signal and extracranial velocity signal. The absolute value of the intracranial pressure is identified as that external pressure at which such equalization occurs.

  • Patent number: 7771356
    Abstract: A system and method for examining a patient for an ear disorder. Reflectance ultrasound is applied to a portion of the ear to determine the presence of ear effusion in a middle ear. If ear effusion is present, motion of the tympanic membrane is induced and ultrasound is further applied to the moving tympanic membrane. Echo signals resulting from the ultrasound applied to the moving tympanic membrane are analyzed to obtain information regarding the motion of the tympanic membrane and is used to characterize the ear effusion.
