| 3 | Regional characteristics of ultrasonic structural scattering in liver显示文摘In this paper, the ultrasonic spectra of liver’s structural scattering wave obtained by autoregressive model and the spectral characteristics were analyzed statisticaJly The experimellt and analysis results show that a liver can be divided into three distingulshed scattering regions. The top layer region shows approkimate Rayleigh scattering characteristic, the central region shows diffosion scattering, and the region between the top layer and centre shows random scattering. These distribution characteristics correlate with the distribution of the microstructure characteristics of liver. The experiment results provide possibilities for tissue recognition using spectrum characteristics of the regional structure scattering. | CHEN Qimin ZHANG Xiaofei LIU Binsheng YAN Bige and LIU Chunrong(Applied Acoustics Institute, Shaanxi Teachers University Xi’an, 710062)(Technical College of the Chinese People’s Armed Police Force, Xi’an, 710086) | 1996 | Chinese Journal of Acoustics1996，15，2： | 0 |
