Rapid Identification Of Microbial Agents

View page
US Patent:
20060259249, Nov 16, 2006
Filed:
Mar 3, 2005
Appl. No.:
11/073362
Inventors:
Rangarajan Sampath - Encinitas CA, US
Vivek Samant - Encinitas CA, US
Christian Massire - Carlsbad CA, US
Harold Levene - San Diego CA, US
David Ecker - Encinitas CA, US
John McNeil - La Jolla CA, US
International Classification:
G06F 19/00
US Classification:
702020000
Abstract:
The method described herein relate generally the identification of bioagents on the basis of base composition signatures for bioagent-identifying amplicons. Specifically, methods of the present invention are directed to the application of pattern recognition models, particularly probability pattern classifiers, to the identification of both known and previously unrecognized bioagents. In certain embodiments, the pattern classifiers relate to probability cloud patterns, such as mutational probability patterns. In other embodiments the pattern classifiers relate to polytope pattern models.

Method For Processing Real-Time Contrast Enhanced Ultrasonic Images

View page
US Patent:
57432660, Apr 28, 1998
Filed:
Apr 25, 1995
Appl. No.:
8/428723
Inventors:
Harold Levene - San Diego CA
Bob Webster - Carlsbad CA
Assignee:
Molecular Biosystems, Inc. - San Diego CA
International Classification:
A61B 800
US Classification:
12866202
Abstract:
The present invention is a novel method for producing real-time colorized, contrast enhanced images from a sequence of grey-scale video images obtained during diagnostic ultrasound. The particular colorizing scheme varies according to which information parameter is desired to be displayed in real-time. The information parameters used to colorize a segment of video images include: time-to-arrival, duration of brightening, and absolute brightening. Time-to-arrival colorization depicts the time that a given pixel achieves a given intensity threshold. Duration of brightening depicts the time that a given pixel's intensity stays above a given threshold. Absolute brightening depicts various threshold values obtained by the region's pixels.

Analysis Of Ultrasound Images In The Presence Of Contrast Agent

US Patent:
57760632, Jul 7, 1998
Filed:
Sep 30, 1996
Appl. No.:
8/723898
Inventors:
Howard Dittrich - San Diego CA
Harold Levene - San Diego CA
Eric Mjolsness - Encinitas CA
Assignee:
Molecular Biosystems, Inc. - San Diego CA
International Classification:
A61B 500
A61B 800
US Classification:
600408
Abstract:
A method and apparatus for directly identifying and characterizing input data derived from regions of interest in ultrasound images of organs in the presence of attenuation from interposed contrast agent, for the purpose of diagnosing abnormalities. The input data is classified into one of a number of classes depending upon the characteristics of that data, in order to distinguish normal conditions from abnormal conditions. The invention is based on the recognition that significant information relating to the health of tissue exists in regions of interest in ultrasound images in the presence of attenuation from interposed contrast agent. This information is in the form of backscatter speckle patterns that have "texture" characteristics that are distinguishable in healthy versus diseased tissue. The invention classifies such patterns as probably normal or abnormal by means of an analysis system that may include a neural network system. The preferred embodiment of the present invention includes: (1) a data acquisition system for acquiring ultrasound image data indicative of a region of interest in the presence of attenuation from interposed contrast agent; (2) an optional signal conditioning stage to remove signals (e. g.

Method Of Ultrasonically Quantitating Myocardial Perfusion Using As Intravenously Injected Tracer

View page
US Patent:
57327076, Mar 31, 1998
Filed:
Jun 5, 1996
Appl. No.:
8/659542
Inventors:
Kenneth J. Widder - Rancho Santa Fe CA
Harold B. Levene - San Diego CA
Gary L. Bales - San Diego CA
Assignee:
Molecular Biosystems, Inc. - San Diego CA
International Classification:
A61B 800
US Classification:
12866108
Abstract:
Myocardial perfusion is assessed quantitatively by an ultrasonic echocardiographic procedure in which: the myocardium is ultrasonically imaged; an ultrasonic contrast agent consisting of a suspension of pressure-stable, water-insoluble gas-containing microspheres sized to pass through the pulmonary capillaries is injected intravenously; imaging is continued through the first transit of the microspheres through the myocardium; the videodensity versus time relationship is determined from the images; and blood flow through the myocardium is calculated from that relationship.

Method Of Ultrasound Imaging Of The Gastrointestinal Tract

View page
US Patent:
51078422, Apr 28, 1992
Filed:
Feb 22, 1991
Appl. No.:
7/660349
Inventors:
Harold B. Levene - San Diego CA
Elaine Villapando - San Diego CA
James L. Barnhart - Encinitas CA
Kenneth J. Widder - Del Mar CA
Assignee:
Molecular Biosystems, Inc. - San Diego CA
International Classification:
A61B 814
US Classification:
12866202
Abstract:
A method is provided for enhanced ultrasonic imaging of the gastrointestinal tract by employing an imaging agent comprising an aqueous particulate dispersion of edible substances, such as insoluble brans and mineral particles. Hydrocolloid particles can also be used, preferably in combination with insoluble non-swelling edible particles.

Method Of Abdominal Ultrasound Imaging

View page
US Patent:
51799553, Jan 19, 1993
Filed:
May 28, 1991
Appl. No.:
7/706323
Inventors:
Harold B. Levene - San Diego CA
James L. Barnhart - Encinitas CA
Kenneth J. Widder - Del Mar CA
Assignee:
Molecular Biosystems, Inc. - San Diego CA
International Classification:
A61B 800
US Classification:
12866202
Abstract:
Abdominal ultrasound imaging is carried out by oral or rectal administration of an aqueous imaging agent containing micron size clay particles together with a sufficient amount of a solubilized hydrocolloid to maintain the particles in suspension. The walls of the stomach, duodenum and colon become coated with the clay particles and are thereby more clearly delineated by the ultrasonic imaging beam. At the same time, ultrasonic waves partially pass through the walls and delineate structures outside thereof. Wall delineation and wall transparency can thereby be simultaneously achieved.
