  • Patent number: 11432801
    Abstract: A method and system are provided for guiding a needle to a target location within a subject. The system comprises a probe and a needle guide. The probe includes two or more transducers that are arranged to direct sound waves toward a target location on a subject. The needle guide can be detachably coupled to the probe, and may be used to maintain the needle within viewing planes of the transducers while the needle is inserted into the subject. To facilitate guidance of the needle, a real-time image of the target region can be produced by overlaying images produced by the two or more transducers. Such a system may provide a more adaptive and reliable way to guide the insertion of a needle, allowing for more sophisticated and fool-proof viewing planes, improved versatility, and more ergonomic needle control.

  • Patent number: 11432805
    Abstract: Vector Doppler Imaging (VDI) improves on conventional Color Doppler Imaging (CDI) by giving speed and direction of blood flow at each pixel of a display generated by a computing system. Multiple angles of Plane wave transmissions (PWT) via an ultrasound transducer conveniently give projected Doppler measurements over a wide field of view, providing enough angular diversity to identify velocity vectors in a short time window while capturing transitory flow dynamics. A fast, aliasing-resistant velocity vector estimator for PWT is presented, and VDI imaging of a carotid artery with a 5 MHz linear array is shown using a novel synthetic particle flow visualization method.
