Patent number: 11443422Abstract: A system includes a processor and, a computer-readable tangible storage device storing program instructions for execution by the processor. The program instructions include instructions for receiving ultrasonic derived data comprising an ultrasound image, representing a region of interest, and radio frequency “(RF”) data associated with the ultrasound image, and instructions for analyzing the RF data to identify at least one feature associated with a region of interest, including either or both of a feature representing a two-dimensional spectrum feature and a feature based on a cepstrum determined from the RF data. The program instructions further include instructions for classifying the region of interest as one of a plurality of anatomical classes from the identified at least one feature and causing a display to display the anatomical class.Type: GrantFiled: October 15, 2018Date of Patent: September 13, 2022Assignee: THE CLEVELAND CLINIC FOUNDATIONInventors: Russell J.

Publication number: 20220099674Abstract: A method for detecting viral or bacteriological pathogens is disclosed. The method comprises collecting a potentially pathogenic sample via a collector, binding a first portion of the potentially pathogenic sample to a magnetic particle via a first coating on the magnetic particle, binding a second portion of the potentially pathogenic sample to a fluorescently labeled particle via a coating of a second coating on the fluorescently labeled particle to create aggregates comprising the potentially pathogenic sample, magnetic particle, and the fluorescently labeled particle, separating the aggregates magnetically, detecting a fluorescence of the separated aggregates, and estimating an amount of the pathogen based on the detected fluorescence.Type: ApplicationFiled: September 29, 2021Publication date: March 31, 2022Inventors: David Geoffrey Vince, Aaron J.

Patent number: 9055921Abstract: A system and method are disclosed that facilitate generating visual representations of characterized tissue based upon ultrasound echo information obtained from a portion of an imaged body. The system includes a first filter having a first filter band that is applied to a near range portion of the ultrasound echo information to render near range filtered echo information. A second filter, having a second filter band that covers a frequency range of the first filter band, is applied to a far range portion of the ultrasound echo information to render far range filtered echo information. The system furthermore includes a set of characterization criteria that are applied to the near and far range filtered echo information. The characterized near and far range image data are thereafter combined into a single tissue-characterization image.Type: GrantFiled: April 22, 2013Date of Patent: June 16, 2015Assignee: Volcano CorporationInventors: Anuja Nair, David Geoffrey Vince, Marja Pauliina Margolis, Kendall Rand Waters

Patent number: 8808183Abstract: A system and method is provided for using ultrasound data backscattered from vascular tissue to estimate the transfer function of a catheter (including components attached thereto—e.g., IVUS console, transducer, etc.). Specifically, in accordance with a first embodiment of the present invention, a computing device is electrically connected to a catheter and used to acquire RF backscattered data from a vascular structure (e.g., a blood vessel, etc.). The backscattered ultrasound data is then used, together with an algorithm, to estimate the transfer function. The transfer function can then be used (at least in a preferred embodiment) to calculate response data for the vascular tissue (i.e., the tissue component of the backscattered ultrasound data). In a second embodiment of the present invention, an IVUS console is electrically connected to a catheter and a computing device and is used to acquire RF backscattered data from a vascular structure.Type: GrantFiled: September 9, 2010Date of Patent: August 19, 2014Assignee: The Cleveland Clinic FoundationInventors: Anuja Nair, David Geoffrey Vince, Jon D. Klingensmith, Barry D. Kuban

Publication number: 20130066212Abstract: A patient's physiological parameters, ascertained using intravascular ultrasound (IVUS) in combination with virtual histology (VH), are evaluated to predict whether the patient's physiology has an increased risk of producing a Clinical Event or a Silent Clinical Event. In one embodiment, one or more physiological parameters, such as Plaque Burden, Minimum Lumen Area, and whether or multiple VH-TCFAs are present, are compared to target values and/or ranges. A concurrence of the values for the physiological parameters to the target ranges indicates that a patient's physiology has an increased risk of producing a Clinical Event or a Silent Clinical Event.Type: ApplicationFiled: September 25, 2010Publication date: March 14, 2013Applicant: Volcano CorporationInventors: Marja Margolis, David Geoffrey Vince, Anuja Nair

Patent number: 6381350Abstract: An intravascular ultrasound (IVUS) analysis system and method is provided which determines luminal and medial-adventitial boundaries of a blood vessel. Ultrasonic data is acquired by a rotating transducer mounted to a tip of a catheter which is inserted into the blood vessel. An intravascular image is reconstructed from the ultrasound data. To determine the luminal boundary of a vessel, a user selects boundary points on the image believed to be locations of the luminal boundary. A boundary contour is generated based on the boundary points. The boundary contour is then optimized by adjusting the boundary points based on a radially determined edge of the luminal boundary performed on the image in polar format. Once the final luminal boundary contour is generated, the process is repeated to determine the medial-adventitial boundary contour. With the contour data, properties of the blood vessel are analyzed including determining the area of the lumen and percent of occlusion caused by plaque.Type: GrantFiled: July 2, 1999Date of Patent: April 30, 2002Assignee: The Cleveland Clinic FoundationInventors: Jon D.
