Non-invasive diagnostic method for atherosclerotic lesious

1.测量信号操作的处理算法的决定除了超声回波线性扫描探头之外，使用凸型传感器使我们能够测量吻合的顺应性不匹配，即使在更近端的动脉或腹部器官的动脉中。我们开始开发处理系统，以快速操作这些测量，并在测量系统上建立了选择装置，用于寻找血流方向因子与垂直矢量的相位差，在操作系统上对装置控制和信号分析程序进行了改进总体上.我们目前正在确认程序上的操作和处理bug，并超过研发计划.关于流动波传播的方向的因素关于流动波的传播，通过引入凸型传感器，我们检查了流动波传播形式的搜索，虽然，从心电图和动脉脉搏波测量速度和粘弹性，将其与由血流速度和搏动引起的动脉壁运动进行匹配并进行分析，并对算法进行了研究，编制了相应的程序除了心电图和脉搏波外，还从粘弹性和波速两个点测量吻合口顺应性失配.临床应用的安全性、实用性的确定我们将用以前开发的BASIC语言并行原程序的测量和用本次开发的通用系统程序并行测量中的操作确定。针对临床应用，我们改进了手术方案和选择装置，保证了手术的安全.

1. The decision of processing algorithm for operation of the measurement signal In addition to ultrasound echo linear scan probe, using a convex type transducer enabled us to measure the compliance mismatching of anastomosis even in a more proximal artery or arteries for abdominal organs.We started the development of processing system for rapidly operation of these measurement, and made option device established at the measurement system to seek for phase difference between blood flow direction factor and that of the vertical vector.We improve the program for device control and signal analysis as working on the operating system which is used generally.We are confirming the operation and processing the bug on the program currently, and exceed a plan of research and development.2. About the factor of direction of flow wave propagationAbout propagation of flow wave, by introduction of convex type transducer, we examine the search for propagation form of the flow wave, though, measuring speed and viscoelastisity from an electrocardiogram and arterial pulse wave, we were to match it with movement of artery wall by blood flow velocity and beat and to analyze it.Algorithm is investigated with the development of the program to measure compliance mismatching of anastomosis from two points viscoelastisity and wave velocity in addition to an electrocardiogram and pulse wave.3. Safety to clinical application, ascertainment of practicalityWe will parallel the measurement by original program by basic language developed formerly and the operation ascertainment in measurement by the program on general system developed this time. For clinical application, we improve program and option device for an operation and security of safety.
