本文介绍了在计算机断层扫描 (CT) 胸部检查期间获得的剂量测定结果，这些检查使用两种不同的技术进行，即顺序 CT (SQCT) 和螺旋 CT (HECT)。放射学检查是在专门设计和实现的儿科模型上进行的。根据0、2、6、12岁儿童的体形，实现了四种不同的模型。剂量测定是使用热释光剂量计进行的。使用两种不同技术获得的剂量测定数据的比较表明，就入口剂量和关键器官接收的剂量而言，它们之间没有任何相关差异。
This paper presents the dosimetric results obtained during computed tomography (CT) thorax examinations, carried out using two different techniques, i.e., sequential CT (SQCT) and helical CT (HECT). The radiological examinations have been carried out on pediatric phantoms expressly designed and realized. Four different phantoms have been realized, according to the children shapes of 0, 2, 6, and 12 years old. The dosimetric measurements have been carried out using thermoluminescent dosimeters. The comparison of the dosimetric data obtained using the two different techniques shows that there is not any relevant difference between them as far as the entrance dose and the doses received by the critical organs are concerned.
