Patent number: 9731323Abstract: The use of power-efficient transmitters to establish acoustic wave energy having low undesirable harmonics is achieved by adjusting the transmitter output waveform to minimize the undesirable harmonics. In one embodiment, both the timing and slope of the waveform edges are adjusted to produce the desired output waveform having little or no second harmonics. In the embodiment, output waveform timing adjustments on the order of fractions of the system clock interval are provided. This then allows for very fine control of a coarsely produced waveform. In one embodiment, the user can select the fine tuning to match the transmitter output signal to a particular load transducer.Type: GrantFiled: October 19, 2015Date of Patent: August 15, 2017Assignee: FUJIFILM SonoSite, Inc.Inventors: John R. Stice, Yanwei Wang, Clinton T. Siedenburg, Andrew K. Lundberg, Justin Coughlin, Max Nielsen

Patent number: 9671491Abstract: Disclosed are systems and methods which efficiently control storage of and/or access to data which includes repetitive data or data which is used by different modes, processes, etcetera. Embodiments provide control for storage of and/or access to large amounts of data used in ultrasound system beam forming for image generation using a hierarchy of sequencers for controlling storage of and/or access to data. A frame sequencer may provide control at a frame level while an address sequencer is implemented to provide control at a data access level.Type: GrantFiled: October 5, 2015Date of Patent: June 6, 2017Assignee: FUJIFILM SonoSite, Inc.Inventors: Blake Little, Thomas Duffy, Justin Coughlin

Patent number: 6135961Abstract: A hand held ultrasonic instrument is provided in a portable unit which performs both B mode and Doppler imaging. The instrument includes a transducer array mounted in a hand-held enclosure, with an integrated circuit transceiver connected to the elements of the array for the reception of echo signals. A digital signal processing circuit performs both B mode and Doppler signal processing such as filtering, detection and Doppler estimation, as well as advanced functions such as assembly of multiple zone focused scanlines, synthetic aperture formation, depth dependent filtering, speckle reduction, flash suppression, and frame averaging.Type: GrantFiled: October 6, 1998Date of Patent: October 24, 2000Assignee: SonoSite, Inc.Inventors: Lauren S. Pflugrath, Jacques Souquet, Blake W. Little, Juin-Jet Hwang, William R. Ogle, Larry Greisel, Justin Coughlin, Steven G. Danielson
