摘要
乳腺组织微观结构的准周期性可以利用散射体平均间距来描述，本文利用ＡＲ倒谱方法对连体正常与病变乳腺组织的散射体平均间距进行了估计，得到了正常乳腺组织的散射体平均间距约为１２５±０２１ｍｍ，各类病变组织的平均间距较正常组织有明显的特异性。
The quasiperiodicity of
microstructure of breast tissue can be described by mean scatterer spacing. In this paper, the
mean scatterer spacing of normal and pathologic human breasts was estimated in vivo using
the AR cepstrum. The mean scatterer spacing averaged 1.25±0.21mm, whereas abnormal
breasts had different mean scatterer spacing. The results obtained showed good correlation
with tissue histologies.
