Radiation visualization is an indispensable technology for accurate dose distribution evaluation in cancer treatment using radiation. We have developed a new measurement system that combines a white organic EL light or inorganic EL source specialized for PVA-KI gel dosimeters with a digital camera using a macro lens. X-ray irradiated PVA-KI gel was imaged with this system. The captured image was converted to RGB values. The relationship between converted RGB values and absorbed dose was clarified.
