摘　　要：超声弹性成像技术是近20年来在医学超声领域出现的新技术,它利用准静态压力、外加低频振动、声辐射力等形式激励组织振动,然后用超声方法检测组织的形变或者由振动引起的剪切波传播,最终得到组织的生物力学特性。超声弹性成像已经被广泛应用在乳腺、肝脏、前列腺等领域,显示了良好的临床应用前景。此外,超声图像处理与分析是超声成像系统的重要组成部分,主要包括超声图像的三维可视化、预处理、分割、配准及图像理解等,旨在为临床医生诊断提供有效的辅助手段。Ultrasound elastography has become a new technique in the medical ultrasound field during the last decades.It stimulates human tissues vibration through different methods,such as quasi-static compress,low frequency vibration and acoustic radiation force,and detects the tissue strain or shear wave propagation by ultrasound to final obtain biomechanical properties of tissues.Ultrasound elastography has been widely applied in the diagnosis of breast,liver and prostate,demonstrating its great potential in clinical applications.Furthermore,as one of the important components of ultrasound imaging systems,ultrasound image processing and analysis,including 3D rendering,pre-processing,segmentation,registration,image understanding and so on,is designed to help the diagnosis of clinicians as an effective auxiliary method.
