This paper presents a model for the estimation of the effective patient dose in computed tomography. It is demonstrated how equivalent organ doses for selected examination can be estimated on the basis of the scanner-specific axis dose and published conversion factors. Problems and limitations of this method are discussed. The determination of the effective dose from the organ equivalent dosis is explained. The explanations are illustrated by an exemplary calculation, and the doses of the most important CT examinations are summarised.
本文提出了一种用于估算计算机断层扫描中有效患者剂量的模型。展示了如何根据特定扫描仪的轴向剂量和已发表的转换因子来估算选定检查的等效器官剂量。讨论了该方法的问题和局限性。解释了如何从器官等效剂量确定有效剂量。通过一个示例计算对这些解释进行了说明，并总结了最重要的CT检查的剂量。
