摘要
In this paper a new method of ultrasonic quantitative diagnosis is discribed. This method can elminate the effect of system deviation and lessen the the effect of beam radiation diffraction. In can be spplied together with many kinks of B-scanners. To verify the method, this paper has shown a new method to make a tissue phantom and a special apparatus. The results show that the method is useful in the diagnosis of diffuse liver diseases, tumors and cancers.It is also useful in the appraisal of the health and the stages of fetus.
