| Research Abstract |
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.
