国外发表过不少关于人体组织超声传播特性的研究文章.我们运用两种较简便的方法——脉冲时标法和正弦连续波共振法,成功地进行了人体组织声速的测量.其方法原理简单,技术不复杂,采用常用设备即可.由于采取了一些技术措施,测量精度达0.1—0.3％,便于推广.本文仅介绍第二种方法的技术. Foreign published a number of research articles on the characteristics of human tissue ultrasound transmission.We use two simple methods - pulse time scale method and sinusoidal continuous wave resonance method, the successful measurement of the body tissue velocity.The method is simple , The technology is not complicated, using common equipment can.Because of some technical measures taken, the measurement accuracy of 0.1-0.3%, easy to promote.This article describes only the second method of technology.
