To present the importance of evaluating the patient’s maximum skin dose in real-time, to reduce the risk of radiation injury in interventional radiology (IR). To discuss the devices used to measure the patient dose in IR and the advantages/disadvantages of these devices. To demonstrate the usefulness of a new real-time measurement device for patient dose during IR.

Advantages/limitations of real-time patient dose-measuring devices Skin dose monitor, patient skin dosimeter, MOSFET dosimeter, etc., were evaluated. Performance comparison among real-time patient dose-measuring devices Energy dependence, linearity, dose-rate dependence, angular dependence, invisibility of sensor and cable in X-ray images, etc., were studied. Development of a new device for real-time measurement of patient radiation dose The real-time skin dosimeter (RSD) device consists of a photoluminescence sensor, optical fiber, photodiode, and display. OUTLINE: During IR, patients can be injured due to long-term X-ray radiation exposure. To date, no feasible method exists for measuring the radiation dose to the patient in real-time during IR. We developed a novel real-time patient dosimeter for IR procedures.The RSD offers good fundamental characteristics, including high sensitivity, and only a slight energy and dose-rate dependence.
