关于医学超声诊断成像的机理与建模探讨

Review and Modeling on the Ultrasound Imaging in Medical Diagnosis

本文从医学超声诊断的成像机理上综述和探讨了超声波在医学中的应用,以期探讨超声回波所携带信息的描述。首先,本文介绍了超声波的发展史和利用超声波进行诊断的理论依据,以及目前的几种类型的超声波,然后,主要推导了超声波的波动方程和多普勒超声波的数学模型。

A brief review and some discussions are made on the principle of ultrasound imaging in medical diagnosis on that in order to get the representation of the information from the echoes. First, the history and the theory of ultrasound aided diagnosis and the types of ultrasound used now are introduced. And then the vibration equations of ultrasound and the mathematical modeling of Donnler ultrasound are analyzed.
