摘要
目的 :为医学超声诊断水平的提高。方法 :以超声传播所遵循的物理规律、超声成像的物理原理以及医学超声诊断仪的基本设置为基础 ,佐以实验观察 ,系统地分析了影响超声回波强度的因素和规律并重点讨论了介质薄层的透声规律。结果与结论 :超声回波的强度可受多种因素的影响 :提出“介质薄层伪像”和“隐现声影”
Objective:To improve the level of ultrasonic diagnosis.Methods:Based on the law of ultrasonic transmission,principle of ultrasonic imaging,basic structure of ultrasonic diagnostic apparatus and experimental observation,influencing factors in ultrasonic echo intensity and the transmission law of medium lamella were systematically analyzed.Results and Conclusion:There are many influencing factors in ultrasonic echo intensity.New concepts such as medium lamella artifact are brought forward.
