医学超声非线性成像方法可行性研究

Research on the Feasibility of Medical Ultrasound Nonlinear Imaging Method

非线性成像能够区分出组织的组份、结构及病理的变化,因此该方法作为诊断组织是否病变在临床医学中有着重大的应用。介绍一种基于脉冲回波系统模型的超声非线性成像方法,讨论该方法所用的医学超声系统的线性范围,确定其工作电压及增益范围,证明该方法在超声系统上实现的可行性和有效性。

Nonlinear imaging can distinguish changes in components, structure and pathological state of a tissue, as a result, this method has impor-tant application in clinical medicine for judging the lesion is health or not. Introduces a nonlinear imaging method based on pulse echo system model, discusses the linear range of the medical ultrasound system used in this method, and determines the system operating volt-age and gain range, proves the feasibility and effectiveness of the method in the medical ultrasound system.
