Patent number: 9060669Abstract: An ultrasonic imaging method includes activating a transmit aperture within a multi-element transducer array, transmitting one or more ultrasonic beams along scan direction(s) that span the region of interest, for each transmit event, receiving ultrasound echoes from each element of a receive aperture, grouping the receive channel echo data into two or more sets corresponding to different receive sub-apertures, combining each sub-aperture data set to generate partially focused echo-location data for one or more reconstruction lines, and storing all the sub-aperture echo data sets during a storage period in a format that can be retrieved for later analysis.Type: GrantFiled: December 19, 2008Date of Patent: June 23, 2015Assignee: ZONARE MEDICAL SYSTEMS, INC.Inventors: Larry Y.

Publication number: 20150087983Abstract: Methods of probing a material under investigation using an ultrasound beam. Echolocation data is generated using a multi-dimensional transform capable of using phase and magnitude information to distinguish echoes resulting from ultrasound beam components produced using different ultrasound transducers. Since the multi-dimensional transform does not depend on using receive or transmit beam lines, a multi-dimensional area can be imaged using a single ultrasound transmission. In some embodiments, this ability increases image frame rate and reduces the amount of ultrasound energy required to generate an image.Type: ApplicationFiled: May 5, 2014Publication date: March 26, 2015Applicant: ZONARE Medical Systems, Inc.Inventors: Glen McLaughlin, Ting-Lan Ji, David Napolitano

Patent number: 7699781Abstract: A system for ultrasonic imaging utilizing multiple sets of transmit pulses differing in amplitude, frequency, phase, and/or pulse width. One embodiment has phase differences between the k transmit signal as 360 k ? ? degrees providing for constructive interference of the kth order harmonic pulse, while an amplitude modulation of each transmit profile is constant between sets. These sets of pulses are transmitted into media of interest and received echoes from these pulses are combined to form an averaged signal. The averaged pulses represent the net common mode signal received from each of the transmit sets. This combined signal set is used to reconstruct an ultrasound image based on broad beam reconstruction methodology.Type: GrantFiled: February 4, 2004Date of Patent: April 20, 2010Assignee: ZONARE Medical Systems, Inc.Inventors: Glen McLaughlin, Ting-Lan Ji

Patent number: 7682309Abstract: An ultrasound imaging system configured to simultaneously acquire and process multi-mode and multi-band echo information from a single set of pulse firings is provided. Raw ultrasound signals are digitized and stored in an I/Q data buffer. The stored data are then parallel preprocessed as a function of frequency band or alternative encoding. Parallel preprocessing optionally includes manipulating the data in respect to different imaging modes. Outputs of the parallel preprocessors are coupled to separate area formers used to simultaneously reconstruct various desired echo information to form a multi-mode or multi-band image. The echo formation process is optionally performed in parallel.Type: GrantFiled: January 25, 2005Date of Patent: March 23, 2010Assignee: ZONARE Medical Systems, Inc.Inventors: Ting-Lan Ji, Glen McLaughlin

Patent number: 7361145Abstract: Systems of generating and manipulating an ultrasound beam are disclosed. The system uses selective sets of ultrasound elements to generate an ultrasound beam, scanning the beam over a series of ultrasound elements in order to collected echo data covering an area, and generating an image from the resulting data. The scanning process includes shifting the set of ultrasound elements used to form the ultrasound beam by more then one ultrasound element (block-switching) between each step in the scanning process. This is accomplished without loss of image resolution by using area-forming techniques. The block-switching technique enables use of cross-correlation methods during image construction.Type: GrantFiled: July 16, 2004Date of Patent: April 22, 2008Assignee: ZONARE Medical Systems, Inc.Inventors: Xufeng Xi, Glen McLaughlin, Umit Tarakci
