Ultrasonic Technique For Assessing Wall Vibrations In Stenosed Blood Vessels

View page
US Patent:
7736314, Jun 15, 2010
Filed:
Aug 31, 2005
Appl. No.:
11/218292
Inventors:
Kirk W. Beach - Seattle WA, US
Yongmin Kim - Lake Forest Park WA, US
Siddhartha Sikdar - Seattle WA, US
Assignee:
University of Washington - Seattle WA
International Classification:
A61B 8/00
US Classification:
600437, 73584, 181101, 367 87
Abstract:
A real-time signal processing technique for ultrasonic imaging of tissue vibrations for localizing the source of a bruit in a 2D image with respect to the anatomy and/or for obtaining simultaneous information about vibrations and the underlying blood flow. The bruit can be quantitatively assessed using an ensemble of ultrasound echoes. Signal processing enables estimation of wall displacement and the display of time-resolved vibration spectrum. Vibrations are detected and color-coded according to their amplitude and frequency and overlaid on the B-mode and/or color-flow image in real time. Proposed vibration imaging algorithms use data acquired during conventional ultrasonic color-flow imaging and the clutter signal, normally suppressed in color-flow imaging, to detect and characterize tissue vibrations. Three vibration imaging algorithms based on parametric modeling of vibrations and other criteria distinguish between clutter, blood flow, and vibrations. The techniques are usable to detect, locate, image, and quantitatively grade stenoses in blood vessels.

Transcutaneous Localization Of Arterial Bleeding By Two-Dimensional Ultrasonic Imaging Of Tissue Vibrations

View page
US Patent:
7803116, Sep 28, 2010
Filed:
Oct 1, 2004
Appl. No.:
10/574133
Inventors:
Siddhartha Sikdar - Seattle WA, US
Yongmin Kim - Lake Forest Park WA, US
Kirk Beach - Seattle WA, US
Assignee:
University of Washington through its Center for Commericalization - Seattle WA
International Classification:
A61B 8/14
US Classification:
600462, 600437, 600407, 600465, 600468
Abstract:
An ultrasound based technique for detecting and imaging vibrations in tissue caused by eddies produced during bleeding through punctured arteries or from organs. A clutter signal, normally suppressed in conventional color flow imaging, is employed to detect and characterize local tissue vibrations, to detect internal bleeding in an image, or as an audible or palpable signal, or a readout. Using a tissue vibration image, the origin and extent of vibrations relative to the underlying anatomy and blood flow can be visualized in real time, enabling measurements of vibration amplitude, frequency, and spatial distribution. Bleeding rate can be determined from the frequency and amplitude of the vibrations. Signal processing algorithms usable to identify tissue vibrations from an ensemble of 2D ultrasound data include those based on phase decomposition, spectral estimation using eigendecomposition, and spectral estimation using autoregressive modeling for isolating vibrations from clutter, blood flow, and noise.

Interference-Free Ultrasound Imaging During Hifu Therapy, Using Software Tools

View page
US Patent:
20060264748, Nov 23, 2006
Filed:
Sep 16, 2005
Appl. No.:
11/229000
Inventors:
Shahram Vaezy - Seattle WA, US
Robert Held - Issaquah WA, US
Siddhartha Sikdar - Seattle WA, US
Ravi Managuli - Seattle WA, US
Vesna Zderic - Seattle WA, US
Assignee:
University of Washington - Seattle WA
International Classification:
A61B 8/00
US Classification:
600437000
Abstract:
Disclosed herein is a method for obtaining a composite interference-free ultrasound image when non-imaging ultrasound waves would otherwise interfere with ultrasound imaging. A conventional ultrasound imaging system is used to collect frames of ultrasound image data in the presence of non-imaging ultrasound waves, such as high-intensity focused ultrasound (HIFU). The frames are directed to a processor that analyzes the frames to identify portions of the frame that are interference-free. Interference-free portions of a plurality of different ultrasound image frames are combined to generate a single composite interference-free ultrasound image that is displayed to a user. In this approach, a frequency of the non-imaging ultrasound waves is offset relative to a frequency of the ultrasound imaging waves, such that the interference introduced by the non-imaging ultrasound waves appears in a different portion of the frames.
