Publication number: 20240057971Abstract: Exemplary embodiments provide systems and methods for portable medical ultrasound for transcranial ultrasound imaging. Preferred embodiments utilize a hand portable, battery powered system having a display and a user interface operative to control imaging and display operations. A keyboard control panel can be used alone or in combination with touchscreen controls to actuate a graphical user interface. The system includes a transducer assembly to image, measure and monitor a condition of a patient or deliver a therapeutic signal to the patient.Type: ApplicationFiled: May 11, 2023Publication date: February 22, 2024Applicant: Teratech CorporationInventors: Alice M. Chiang, Noah Berger

Publication number: 20230346344Abstract: The present invention related to an ultrasound imaging system win which the scan head includes a beamformer circuit that performs far field subarray beamforming or includes a sparse array selecting circuit that actuates selected elements. When using a hierarchical two-stage or three-stage beamforming system, three dimensional ultrasound images can be generated in real-time. The invention further relates to flexible printed circuit boards in the probe head. The invention furthermore related to the use of coded or spread spectrum signaling in ultrasound imagining systems. Matched filters based on pulse compression using Golay code pairs improve the signal-to-noise ratio thus enabling third harmonic imaging with suppressed sidelobes. The system is suitable for 3D full volume cardiac imaging.Type: ApplicationFiled: January 20, 2023Publication date: November 2, 2023Inventors: Alice M. Chiang, William M. Wong, Steven R. Broadstone

Patent number: 11547382Abstract: A hand-held ultrasound system includes integrated electronics within an ergonomic housing. The electronics includes control circuitry, beamforming and circuitry transducer drive circuitry. The electronics communicate with a host computer using an industry standard high speed serial bus. The ultrasonic imaging system is operable on a standard, commercially available, user computing device without specific hardware modifications, and is adapted to interface with an external application without modification to the ultrasonic imaging system to allow a user to gather ultrasonic data on a standard user computing device such as a PC, and employ the data so gathered via an independent external application without requiring a custom system, expensive hardware modifications, or system rebuilds.Type: GrantFiled: March 18, 2013Date of Patent: January 10, 2023Assignee: Teratech CorporationInventors: Noah Berger, Michael Brodsky, Mark Laforest, Alice M.
