  • Non-contact acoustic radiation force based (ARF-based) generation of broad bandwidth mechanical waves using air-coupled ultrasound
    Patent number: 11413007
    Abstract: Methods and systems for measuring one or more properties of a soft material employ air transmitted ultrasound that is reflected from the soft material to generate a mechanical wave in the soft material. A method of measuring one or more properties of a soft material includes transmitting ultrasound through air to an interface boundary between the soft material and air. Force is applied to the soft material by reflecting the ultrasound from the soft material. A mechanical wave is generated in the soft material as a result of the force applied to the soft material. Propagation of the mechanical wave in the soft material is measured with an imaging system. One or more properties of the soft material is determined based on the measured propagation of the mechanical wave in the soft material.

  • HANDHELD OPTICAL IMAGING DEVICES AND METHODS
    Publication number: 20220183553
    Abstract: Handheld optical imaging devices and methods are disclosed herein. In an embodiment, an optical coherence tomography (OCT) system includes an OCT probe that is configured as a hand-held probe for imaging an eye of a patient, the OCT probe includes: an OCT optical system configured to direct a source OCT signal to the eye and configured to capture OCT scan signal returning from the eye; and an on-probe display carried by a handle, wherein the on-probe display is configured to display imaging data of the eye of a patient to an operator during OCT imaging.
