OBJECTIVE. To our knowledge, no feasible method exists for real-time measurement of the radiation dose given to the patient during interventional radiology (IR) procedures. Therefore, we produced a prototype of a real-time dosimeter for patients undergoing IR 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, with the exception that our prototype has the distinct advantage of including multichannel sensors. CONCLUSION. The novel real-time dosimeter system is expected to be useful for measuring patient exposure to the radiation dose during IR procedures.
