Different aspects of noise in X-ray computed tomography (XCT) for industrial purposes are examined. An overview of the most common noise metrics is given, together with a description of XCT noise influence quantities. We address the current state of the art in understanding the contribution of noise to XCT measurement uncertainty, giving a chronological view of the different attempts that have been made to account for the contribution from noise to XCT measurement uncertainty. We conclude that approaches to estimating the contribution of noise to XCT measurement uncertainty that account for not only noise, but also other factors that affect image quality (e.g., scattering, beam hardening and blurring) are preferable to approaches that only account for noise.

回顾噪声对X射线计算机断层扫描测量不确定度的影响

检查了工业用途X射线计算机断层扫描(XCT)中噪声的不同方面。概述了最常见的噪声指标,并介绍了XCT噪声影响量。我们在了解噪声对XCT测量不确定度的影响时,介绍了当前的发展水平,以时间顺序的方式说明了为解决噪声对XCT测量不确定度的影响所做的各种尝试。我们得出结论,估计噪声对XCT测量不确定性的影响的方法比仅考虑噪声的方法更可取,该方法不仅考虑了噪声,而且还影响了影响图像质量的其他因素(例如,散射,光束硬化和模糊)。
