松质骨组织的若干超声参量成像方法

Review on the ultrasonic parametric imaging of cancellous bones

介绍了两种松质骨组织超声参量成像方法,即宽带超声衰减成像和超声传导速度成像,概述了这两种基于透射法的成像方法的基本原理以及应用情况,并指出了采用超声透射法参量成像时存在的问题。然后对基于背散射法的超声背散射系数成像方法的可行性进行了分析和讨论,最后对进一步的研究工作进行了展望。

Two ultrasonic parameters imaging methods for cancellous bone are introduced： broadband ul- trasound attenuation imaging and sound speed imaging. The basic principle and practical applications of the two kinds of transmission imaging methods are explained. And some problems on ultrasonic parameter imaging of the transmission method are pointed out. Then the feasibility of ultrasonic backscattering coefficient imaging method is discussed. And an outlook on the further research work is presented.
