摘　　要：本文利用 AR倒谱法对人体正常脾和脾增生组织的回波信号进行了分析 ,对软组织中散射元的平均间距进行了估计 ,结果表明 :两种脾组织散射元的平均间距明显不同 ;AR倒谱能有效的反映软组织的微观结构特征 ,说明The paper applies AR cepstrum to process the back scattered signals of normal and pathological human spleen in vitro,and the mean scatterer spacing(MSS)has been estimated.The results show that the MSS of two tissues is quite different and the AR cepstrum is effective to reflect the microstructure feature of tissue.Therefore,the AR cepstrum can be considered as an effective method for signal analysis of ultrasonic scattering and characterization of tissue scatteres.
