Publication number: 20220139561Abstract: Using a patient's physiological parameters ascertained using standard intravascular ultrasound (IVUS) in combination with virtual histology (VH), these physiological parameters 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 the following three physiological parameters: the Plaque Burden; the Minimum Lumen Area; and whether a VH-TCFA or multiple VH-TCFAs are present are compared to target values and ranges. A concurrence of the values for the physiological parameters falling within the target ranges indicates that a patient's physiology has an increased risk of producing a Clinical Event or a Silent Clinical Event, respectively. In other embodiments, combinations of any two of the three physiological parameters listed above are compared to target values and ranges.Type: ApplicationFiled: September 25, 2010Publication date: May 5, 2022Applicant: VOLCANO CORPORATIONInventors: Marja Pauliina Margolis, Geoffrey Vince, Anuja Nair

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.

Patent number: 8630492Abstract: A system and method are provided for using a first vascular image, or more particularly a plurality of control points located thereon, to identify a border on a second vascular image. Embodiments of the present invention operate in accordance with an intra-vascular ultrasound (IVUS) device and a computing device electrically connected thereto. In one embodiment, the computing device includes a plurality of applications operating thereon that are used to (I) identify a border and control points on a first IVUS image (i.e., any IVUS image), (ii) extrapolate the control points to a second IVUS image (i.e., another IVUS image), (iii) identify a border on the second IVUS image, and (iv) adjust the border on the second IVUS image in accordance with at least one factor.Type: GrantFiled: July 31, 2012Date of Patent: January 14, 2014Assignee: The Cleveland Clinic FoundationInventors: Jon D.

Publication number: 20140012134Abstract: A system and method is provided for using ultrasound data backscattered from vascular tissue to estimate the transfer function of a catheter and/or substantially synchronizing the acquisition of blood-vessel data to an identifiable portion of heartbeat data. The backscattered ultrasound data is used, together with an algorithm, to estimate at least one transfer function. The transfer function(s) 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). The response data and histology data are then used to characterize at least a portion of the vascular tissue (e.g., identify tissue type, etc.). In some embodiments, the backscattered data is acquired during a cyclical portion of the heartbeat data so that the blood vessel can be analyzed or imaged as if it were standing still, or not expanding and relaxing.Type: ApplicationFiled: May 28, 2013Publication date: January 9, 2014Applicants: Cleveland Clinic Foundation, Volcano CorporationInventors: Anuja Nair, Barry D.

Patent number: 8622910Abstract: A system and method is provided for substantially synchronizing the acquisition of blood-vessel data to an identifiable portion of heartbeat data. Specifically, a data-gathering device is adapted to acquire heartbeat data and blood-vessel data from a heart-monitoring device and a data-gathering probe, respectively. In a preferred embodiment of the present invention, the blood-vessel data is acquired during a cyclical portion of the heartbeat data. By identifying a cyclical (or commonly reoccurring) portion of the heartbeat data and acquiring blood-vessel data during this cyclical portion (or during an interval that substantially corresponds thereto), the blood vessel can be analyzed as if it were standing still—i.e., not expanding and relaxing. In one embodiment of the present invention, the heart-monitoring device includes an EKG device, the data-gathering device includes an intra-vascular ultrasound (IVUS) device and a computing device, and the data-gathering probe includes at least one transducer.Type: GrantFiled: April 19, 2011Date of Patent: January 7, 2014Assignee: The Cleveland Clinic FoundationInventors: Barry D.

Patent number: 8303503Abstract: A system and method is provided for using backscattered data and known parameters to characterize vascular tissue. Specifically, in one embodiment of the present invention, an ultrasonic device is used to acquire RF backscattered data (i.e., IVUS data) from a blood vessel. The IVUS data is then transmitted to a computing device and used to create an IVUS image. The blood vessel is then cross-sectioned and used to identify its tissue type and to create a corresponding image (i.e., histology image). A region of interest (ROI), preferably corresponding to the identified tissue type, is then identified on the histology image. The computing device, or more particularly, a characterization application operating thereon, is then adapted to identify a corresponding region on the IVUS image. To accurately match the ROI, however, it may be necessary to warp or morph the histology image to substantially fit the contour of the IVUS image.Type: GrantFiled: June 1, 2006Date of Patent: November 6, 2012Assignee: The Cleveland Clinic FoundationInventors: Anuja Nair, D.
