The global noise (GN) algorithm has been previously introduced as a method for automatic noise measurement in clinical CT images. The accuracy of the GN algorithm has been assessed in abdomen CT examinations, but not in any other body part until now. This work assesses the GN algorithm accuracy in automatic noise measurement in head CT examinations.

头部 CT 检查中自动噪声测量的全局噪声算法评估

全局噪声（GN）算法之前已被介绍为临床 CT 图像中自动噪声测量的方法。GN 算法的准确性已在腹部 CT 检查中得到评估，但迄今为止尚未在任何其他身体部位进行评估。这项工作评估了 GN 算法在头部 CT 检查中自动噪声测量的准确性。
