Patent number: 9402601Abstract: 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: January 30, 2003Date of Patent: August 2, 2016Assignee: TERATECH CORPORATIONInventors: Noah Berger, Michael Brodsky, Alice M. Chiang, Mark LaForest

Publication number: 20150065879Abstract: A system and method for real-time quantitative analysis of heart wall motion is provided. A Doppler imaging system is used to monitor the movement of a heart, or other organ. A B-mode reference image of the target organ is made and then a region-of-interest is defined through the use of a gate. Then pulsed wave spectral tissue Doppler data of the region-of-interest is formed and used to determine the velocity of a region of the target organ. The system may be used for determining appropriate biventricular pacemaker settings for patients suffering from heart disease.Type: ApplicationFiled: November 7, 2014Publication date: March 5, 2015Applicant: Teratech CorporationInventors: Xingbai He, Alice M. Chiang

Publication number: 20130261463Abstract: 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: May 21, 2013Publication date: October 3, 2013Applicant: TERATECH CORP.Inventors: Alice M. Chiang, William M.
