Ultrasound examination of foreign bodies most frequently encountered in the human body was performed when they were contained within a transmission medium acoustically resembling human soft tissues. All the foreign bodies evaluated (lead and plastic pellets, pieces of wire, nails, needles, small fragments of rock and glass, wooden slivers, surgical sponges and surgical threads) were detectable with ultrasound. Strong echoes were reflected from their surface when they were positioned favourably, although in some positions the echoes from a needle, fragment of glass, wooden silver, or surgical thread could not be distinguished from those of the surroundings. Acoustic shadows were also seen behind the foreign bodies. A striking column of reverberation echoes was demonstrated behind lead pellets and nails while behind a glass plate there was an acoustic shadow that was often difficult to detect because it was concealed by a mirror image. With modern grey-scale real-time equipment it is possible to demonstrate objects from various angles, a fact which should facilitate the detection of foreign bodies in vivo circumstances.
当人体中最常见的异物包含在声学上类似于人体软组织的传输介质中时，对其进行了超声检查。所有评估的异物（铅丸和塑料丸、金属丝碎片、钉子、针、岩石和玻璃小碎片、木片、手术海绵和手术线）都可用超声检测到。当它们处于有利位置时，其表面会反射强回声，不过在某些位置，针、玻璃碎片、木片或手术线的回声与周围环境的回声无法区分。异物后方也可见声影。在铅丸和钉子后方显示出明显的一系列混响回声，而在玻璃板后方有一个声影，由于被镜像掩盖，常常难以检测到。使用现代灰阶实时设备，可以从各种角度显示物体，这一事实应有助于在体内情况下检测异物。
