METHOD FOR CHARACTERISING THE STRUCTURE OF A MEDIUM AND APPARATUS THEREFOR |
| 摘要 |
The invention relates to a method for characterizing the structure of a medium in which the ultrasonic absorption coefficient of the medium is measured. In order to perform a spectral analysis of this absorption, the spectrum of the signal reflected after it has been transmitted is evaluated by means of an autocorrelation method. Application: medical practice. |
