Measurements of the ultrasound attenuation were carried out in 10 normal testes and 20 pathologically changed testicular tissue biopsies in vitro after formalin fixation. The ultrasound attenuation as function of the frequency was recorded ultrasound-spectroscopically about the complete frequency spectrum of the ultrasound-broad range transformer (3-8 MHz). The frequency dependence of the attenuation behaviour differed in the 10 normal testes from the 20 pathologically changed biopsies by smaller values of the ultrasound attenuation coefficient a (linear regression analysis). The ultrasound attenuation in a characteristic measuring point allows the differentiation between normal and pathologically changed testicular tissue. The following comparison with the histologic evidences showed the correspondence of the results.
在福尔马林固定后,对10个正常睾丸和20份病理改变的睾丸组织活检样本进行了体外超声衰减测量。使用超声光谱仪记录了超声宽范围换能器(3 - 8MHz)整个频谱范围内超声衰减随频率的变化情况。通过超声衰减系数a的较小值(线性回归分析),10个正常睾丸的衰减行为频率依赖性与20份病理改变的活检样本不同。在一个特征测量点的超声衰减能够区分正常和病理改变的睾丸组织。随后与组织学证据的比较显示了结果的一致性。
