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: 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.

Patent number: 8298147Abstract: A method and system are disclosed for creating, in a coordinated manner, graphical images of a body including vascular features from a combination of image data sources. The method includes initially creating an angiographic image of a vessel segment. The angiographic image is, for example, either a two or three dimensional image representation. Next, a vessel image data set is acquired that is distinct from the angiographic image data. The vessel image data set comprises information acquired at a series of positions along the vessel segment. An example of such vessel image data is a set of intravascular ultrasound frames corresponding to circumferential cross-section slices taken at various positions along the vessel segment. The angiographic image and the vessel image data set are correlated by comparing a characteristic rendered independently from both the angiographic image and the vessel image data at positions along the vessel segment.Type: GrantFiled: June 23, 2006Date of Patent: October 30, 2012Assignee: Volcano CorporationInventors: Richard Scott Huennekens, Vincent J.
