从CT到儿科患者的有效剂量在文献中并不常见。本文报道了CT检查对少女的一些有效剂量。体素计算模型ADELAIDE代表一个14岁的女孩，其大小按+/-5%缩放，以代表11-12岁和16岁的女孩。使用EGS4蒙特卡罗代码计算了从胸部、腹部和整个躯干CT检查到三个版本的阿德莱德使用120 kV频谱的有效剂量。对于整个躯干CT检查，有效剂量依次为9.0、8.2和7.8 mSv / 100 mA.s。数据提出，允许从躯干CT检查的有效剂量的估计为11至16岁之间的女孩。
Effective doses from CT to paediatric patients are not common in the literature. This article reports some effective doses to teenage girls from CT examinations. The voxel computational model ADELAIDE, representative of a 14-year-old girl, was scaled in size by +/-5% to represent also 11-12-year-old and 16-year-old girls. The EGS4 Monte Carlo code was used to calculate the effective dose from chest, abdomen and whole torso CT examinations to the three versions of ADELAIDE using a 120 kV spectrum. For the whole torso CT examination, in order of increasing model size, the effective doses were 9.0, 8.2 and 7.8 mSv per 100 mA.s. Data are presented that allow the estimation of effective dose from CT examinations of the torso for girls between the ages of 11 and 16.
