A real-time radiation monitor using fiber optic technology was applied to measure entrance skin doses received during interventional radiology (IVR). The measured entrance doses were 2.1+0.8 mGy/frame and 384+42 mGy for photography and 28+11 mGy/min and 504+77 mGy for fluoroscopy in 20 patients who received IVR or DSA examinations. This monitor is designed to easily measure entrance skin dose, and thus it can be used for the optimization of radiation protection during IVR. This device would be useful for physicians performing IVR, to prevent deterministic effects such as severe skin damage.
