| Outline of Final Research Achievements |
There are no effective real-time direct skin dosimeters for interventional radiology (IVR). Therefore, we produced a prototype of a real-time dosimeter for patients undergoing IVR that uses a nontoxic phosphor. The basic characteristics of the real-time dosimeter prototype are comparable to those of the previously used skin dose monitor (SDM), with the exception that our prototype has the distinct advantage of including multichannel sensors. The novel dosimeter exhibited equivalent performance with respect to energy dependence and linearity, etc., compared with an SDM.
To date, no feasible method exists for measuring the radiation dose to the patient in real-time during IVR. Therefore, the novel real-time dosimeter system is expected to useful in measuring patients’ exposure dose during IVR.
