Abstract

Equivalent doses for the eye lenses, thyroid, and mammary glands were measured and compared between one adult and three pediatric anthropomorphic phantoms during chest computed tomography (CT) using 40 mm volume helical scan on the Aquilion ONE GENESIS Edition CT equipment. Placing an optically stimulated luminescence dosemeter (OSLD) on the eye lenses, thyroid, and mammary gland, we measured and compared the equivalent dose of OSLD among different phantoms during chest CT using a helical scan. Compared with adults, the equivalent doses to the eye lens, thyroid, and mammary glands were ~81%, 77%, and 63% lower in newborns, 1-year-olds, and 5-year-olds using comparable image noise during chest CT.

在使用 40 毫米容积螺旋扫描进行胸部 CT 检查时，比较三个小儿和一个成人拟人模型的眼球镜片、甲状腺和乳腺的等效剂量。

在 Aquilion ONE GENESIS 版 CT 设备上使用 40 毫米容积螺旋扫描进行胸部计算机断层扫描（CT）时，我们测量并比较了一个成人和三个儿童拟人化模型的眼球晶状体、甲状腺和乳腺的等效剂量。我们在眼球镜片、甲状腺和乳腺上放置了一个光刺激发光剂量计（OSLD），测量并比较了不同模型在使用螺旋扫描进行胸部计算机断层扫描时的等效剂量。与成人相比，新生儿、1 岁儿童和 5 岁儿童在胸部 CT 期间使用可比图像噪声时，其眼球晶状体、甲状腺和乳腺的等效剂量分别降低了约 81%、77% 和 63%。

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
