The correct interpretation of echo amplitude patterns of high-resolution gray scale ultrasonograms of the breast requires the use of calibrated color-coded isodensitometry, standardized operation of the ultrasound system, amplitude stability of 1 per cent or better, and a constant velocity water-coupled electro-mechanical scanner. The same conditions may be required for correct interpretation of the ultrasonograms of the parenchyma of the liver, spleen, ovaries, testes, uterus, thyroid, and tumors. Color coding is not required and may actually be detrimental in the study of gross ultrasonography anatomy and in disease states that can be identified by simple anatomical distortions. To be of value, rigid standardization and control of the amplitude characteristics and scanning velocity of the system are imperative.
正确解读乳房高分辨率灰阶超声图的回声振幅模式，需要使用校准后的彩色编码等密度测定法、超声系统的标准化操作、1%或更佳的振幅稳定性，以及恒速水耦合机电扫描仪。解读肝脏、脾脏、卵巢、睾丸、子宫、甲状腺及肿瘤实质的超声图时，可能也需要同样的条件。彩色编码并非必需，实际上在大体超声解剖学研究以及可通过简单解剖结构变形识别的疾病状态研究中，它可能是有害的。要发挥作用，对系统的振幅特性和扫描速度进行严格的标准化和控制是必不可少的。
