质量保证 (QA) 测试已被开发为日常监控数字图像分辨率的实用方法。该方法基于称为图像调制M的参数。当存在噪声时，无法直接测量M。相反，测量 M 的有偏估计（指定为 M'）。本报告描述了参数M'在数字图像分辨率的QA监控中的应用。 M' 的测量通常比其他测量更简单，并且在临床 QA 环境中表现优于视觉评估。
A quality assurance (QA) test has been developed as a practical means to routinely monitor digital image resolution. The method is based upon a parameter termed the image modulation M. When noise is present M cannot be directly measured. Instead, a biased estimate of M, designated M', is measured. This report describes the application of the parameter M' to QA monitoring of digital image resolution. A measurement of M' is generally simpler than alternative measurements, and is shown to outperform visual evaluation in the clinical QA environment.
