Abstract
Three case reports illustrate the changes in a distal acoustic interface after transmission of an ultrasonic beam through a tissue containing two different tissue velocities. The "break" created in the distal interface should be recognized and should not be interpreted as representing a pathologic change.
摘要
三个病例报告说明了超声束穿过包含两种不同组织速度的组织后，远端声学界面的变化。远端界面中产生的“中断”应被识别，且不应被解释为代表病理变化。
