Radiation protection is an important issue in interventional radiology (IVR) for which the radiation dose should be monitored. To protect against patient skin injury, the radiation dose should be monitored in real-time. When more than one effective working view is available, a combination of different viewing angles and real-time monitoring of patient dose can be used to prevent any one skin area from receiving excessive radiation, thereby reducing the risk of skin injury. However, no feasible real-time patient dose measuring method has been established. The purpose of this study was to evaluate the feasibility of using real-time dosimeter to measure patient skin exposure dose after exposure to diagnostic X-ray energies during IVR. The real-time dosimeter detector consists of x-ray scintillator, optical fiber and photodiode. The real-time dosimeter was not visible on X-ray images at diagnostic energies. Furthermore, the real-time dosimeter is easy to handle. Therefore, it will be feasible to use the real-time dosimeter at diagnostic X-ray energies for measuring patient dose during IVR.

辐射防护是介入放射学（IVR）中的一个重要问题，需要对辐射剂量进行监测。为了防止患者皮肤损伤，应实时监测辐射剂量。当有一个以上的有效工作视野可用时，可以使用不同视角和实时监测患者剂量的组合来防止任何一个皮肤区域接收过量辐射，从而降低皮肤损伤的风险。然而，没有可行的实时患者剂量测量方法已经建立。本研究的目的是评估在IVR期间暴露于诊断X射线能量后，使用实时剂量计测量患者皮肤暴露剂量的可行性。实时剂量计探测器由X射线闪烁体、光纤和光电二极管组成。在诊断能量下，实时剂量计在X射线图像上不可见。此外，实时剂量计易于操作。因此，在IVR期间使用诊断X射线能量的实时剂量计测量患者剂量是可行的。
