Ultrasound imaging allows detection of pathologic change in muscle on the basis of increased strength of echoes. With current commercial equipment, however, there is no method of quantitation of the echoes representing muscle, and there is lack of uniformity in scanning methodology. We describe a specially constructed scanning system, designed to access the raw echo data directly from the ultrasound transducer, and allow display and measurement of the echo signals on a computer. In a study of 38 boys with Duchenne muscular dystrophy, aged 1 to 11 years, who had an ultrasound scan of the thigh muscle, 32 (84%) had abnormality on quantitation of the ultrasound echoes. The quantitative techniques we describe could easily be incorporated into the design of ultrasound scanners.
超声成像能够基于回声强度的增加来检测肌肉中的病理变化。然而，使用目前的商用设备，尚无对代表肌肉的回声进行定量的方法，并且扫描方法缺乏一致性。我们描述了一种专门构建的扫描系统，其设计目的是直接从超声换能器获取原始回声数据，并允许在计算机上显示和测量回声信号。在一项对38名年龄在1至11岁的杜氏肌营养不良男孩进行的研究中，这些男孩接受了大腿肌肉的超声扫描，其中32名（84%）在超声回声定量分析中存在异常。我们所描述的定量技术可以很容易地纳入超声扫描仪的设计中。
