Computed tomography (CT) is a diagnostic imaging process that uses ionising radiation to obtain information about the interior anatomic structure of the human body. Considering that the medical use of ionising radiation implies exposing patients to radiation that may lead to unwanted stochastic effects and that those effects are less probable at lower doses, optimising imaging protocols is of great importance. In this paper, we used an assembled 3D-printed infant head phantom and matched its image quality parameters with those obtained for a commercially available adult head phantom using the imaging protocol dedicated for adult patients. In accordance with the results, an optimised scanning protocol was designed which resulted in dose reductions for paediatric patients while keeping image quality at an adequate level.
计算机断层扫描（CT）是一种诊断成像方法，它利用电离辐射获取有关人体内部解剖结构的信息。鉴于电离辐射的医学用途意味着让患者暴露于可能导致不良随机效应的辐射中，且这些效应在较低剂量时不太可能发生，因此优化成像方案至关重要。在本文中，我们使用了一个组装好的3D打印婴儿头部模型，并将其图像质量参数与使用针对成年患者的成像方案为市售成人头部模型获得的参数进行匹配。根据结果，设计了一种优化的扫描方案，该方案在保持图像质量处于适当水平的同时降低了儿科患者的剂量。
