本规程描述了对数字和模拟单色信号源的显示和相机系统分辨率进行诊断性重要测量所需的格式、尺寸和对比度。该规程为医疗诊断成像系统的用户提供了一个全面的测试模式，用于日常操作检查和调整焦点、亮度和对比度、分辨率响应、中频条纹、均匀性和线性观察监视器和硬拷贝记录。本规程的目的不是为图像特性（如分辨率、几何和线性、均匀性、荧光粉缺陷等）创建标准。但是，鼓励使用图案作为评估此类图像特性的测量和规格的适当工具。

This practice describes the format, dimensions, and contrast required to make diagnostically significant measurements of the display and camera system resolution for both digital and analog monochrome signal sources. The practice provides users of medical diagnostic imaging systems with a comprehensive test pattern for day-to-day operational checks and adjustments of focus, brightness and contrast, resolution response, mid-band streaking, uniformity, and linearity of viewing monitors and hard copy recordings. This practice is not intended to create a standard for image characteristics such as resolution, geometry and linearity, uniformity, phosphor defects, etc. However, use of the pattern is encouraged as an appropriate tool for evaluating the measurement and specification of such image characteristics.
