摘要： One embodiment of the present system and method is directed to the identification of tissues (140) within a vascular object by analyzing ultrasound data (120, 125) collected from the vascular object by non-invasive scans (105-115). By identifying and characterizing types of tissue from ultrasound data, an assessment can be made about the health condition of a patient without an invasive procedure. Other applications of the present system will also be appreciated including identifying other types of tissues.

摘要： 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 (110) is electrically connected to a catheter (120) 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).
摘要翻译：提供了一种用于使用从血管组织反向散射的超声数据来估计导管（包括附接到其上的部件 - 例如IVUS控制台，换能器等）的传递功能的系统和方法。具体地，根据本发明的第一实施例，计算设备（110）电连接到导管（120）并用于从血管结构（例如，血管等）获取RF背散射数据。然后将后向散射的超声数据与算法一起用于估计传递函数。然后可以使用传递函数（至少在一个优选实施例中）来计算血管组织的反应数据（即背散射超声数据的组织分量）。

摘要： A system and method is provided for using a first vascular (20) image, or more particularly a plurality of control points (22) located thereon, to identify a border (64) 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. Specifically, in one embodiment of the present invention, an IVUS console is electrically connected to a computing device and adapted to acquire IVUS data. The IVUS data (or multiple sets thereof) is then provided to (or acquired by) the computing device (120). In one embodiment of the present invention, the computing device includes a plurality of applications operating thereon -- i.e., a border-detection application (122), an extrapolation application (124), and an active-contour application (126). These applications 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. In one embodiment of the present invention, the at least one factor is selected from a group consisting of gradient factor, continuity factor, and curvature factor.

摘要： 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 (120) 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 (130) 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 (130), or more particularly, a characterization application (132) 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. After the corresponding region is identified, the IVUS data that corresponds to this region is identified. Signal processing is then performed and at least one parameter is identified. The identified parameter and the tissue type (e.g., characterization data) is stored in a database (134).
