RGB解析法を用いたPVA-KIゲル線量計の線量評価研究

Abstract

In cancer treatment using radiation, radiation visualization is an essential technology for accurately evaluating dose distribution. In this research, we developed a new measurement system that combines a blue organic EL light source specialized for PVA-KI gel dosimeters and a digital camera using a macro lens. Using this system, we imaged a PVA-KI gel irradiated with X-rays. The captured image was converted to RGB values. By comparing the photon count results obtained by ultraviolet–visible spectroscopy with the B value of RGB values, we clarified the relationship between the B value and the absorbed dose.departmental bulletin pape
