Abstract

Patient dose and dose distribution during neurological computed tomography examinations were determined with five different computed tomography scanners. Maximum intracranial doses ranged from 1.17 to 2.67 rads. Doses to the lens of the eye ranged from 0.23 to 2.81 rads. These levels are considered and compared with patient doses reported for other computed tomography studies and for conventional tomographic examinations. In general, patient dose during computer tomographic examinations is less than one quarter of that during conventional tomography of the head.

摘要

使用五台不同的计算机断层扫描仪测定了神经计算机断层扫描检查期间的患者剂量和剂量分布。颅内最大剂量范围为1.17至2.67拉德。眼部晶状体的剂量范围为0.23至2.81拉德。对这些剂量水平进行了考量，并与其他计算机断层扫描研究和传统断层扫描检查报告的患者剂量进行了比较。一般来说，计算机断层扫描检查期间的患者剂量不到头部传统断层扫描期间剂量的四分之一。
