Objective: To testify the reliability of myocardial backscatter intensity measured by commercial ultrasonography.
目的：验证商用超声诊断仪所测定的心肌背向散射信号强度的可靠性。
The concentration of suspended particles in water can be estimated by inversion of the backscatter intensity with the acoustic telemetering system.
声遥测水中悬浮粒子（如泥沙）的反向散射强度，可反演获得粒子浓度。
