Computed tomography (CT) exams are increasingly common and account for a significant portion of individuals' mounting exposure to medical radiation.
To explore issues surrounding patient radiation dose, including techniques for minimizing dose and the feasibility of tracking lifetime exposure to medical radiation from CT and other imaging exams.
The authors conducted a review of the recent literature to assess current knowledge of dose levels, protocols for minimizing patient dose and possible systems for tracking cumulative dose.
Currently, no regulations are in place to track cumulative patient radiation dose. However, the authors discuss possible means of recording, tracking and storing this data, such as standardizing its inclusion in DICOM headers and transmitting it to electronic personal health records.
More research is needed to develop and implement uniform dose tracking procedures and protocols for minimizing patient dose.
计算机断层扫描（CT）检查越来越普遍，在个人日益增加的医疗辐射暴露中占很大比例。
探讨围绕患者辐射剂量的问题，包括使剂量最小化的技术以及跟踪来自CT和其他成像检查的终身医疗辐射暴露的可行性。
作者对近期文献进行了综述，以评估当前关于剂量水平、使患者剂量最小化的方案以及跟踪累积剂量的可能系统的知识。
目前，尚无跟踪患者累积辐射剂量的法规。然而，作者讨论了记录、跟踪和存储这些数据的可能方法，例如将其纳入DICOM头文件并传输到电子个人健康记录中进行标准化。
需要更多研究来开发和实施统一的剂量跟踪程序和方案，以使患者剂量最小化。
