在对18个不同的正常、良性和恶性乳腺组织的超声衰减的定量测量中，我们发现了显著不同的衰减范围。正如以前的活体研究中所观察到的，除了髓样癌外，在我们使用的1.5至3.0 MHz的频率范围内，恶性组织产生的超声波最多。介绍了衰减率差异的仪器、测量方法、结果和可能的原因。
In quantitative measurements of the attenuation of ultrasound in 18 samples of variously normal, benign, and malignant breast tissue, we found significantly different ranges of attenuation. As observed in previous in vivo studies, with the exception of medullary carcinoma, malignant tissue produces the most attentuation of ultrasound in the frequency range of 1.5 to 3.0 MHz we employed. The apparatus, measurement method, results, and the possible causes of the differences in attenuation are presented.
