Comparisons have been made between a number of routine quality assurance (QA) measurements and a number of related subjective aspects of image quality. These comparisons between lateral resolution and perceived definition, dynamic range and subjective grey-level assessment, and slice thickness and overall image quality appraisal showed very poor correlation. We deduce from this that other QA parameters are needed to quantify good image quality as defined by the operators.
已经对一些常规质量保证（QA）测量与图像质量的一些相关主观方面进行了比较。横向分辨率与感知清晰度、动态范围与主观灰度级评估以及切片厚度与整体图像质量评估之间的这些比较显示出非常低的相关性。我们由此推断，需要其他QA参数来量化操作人员所定义的良好图像质量。
