Abstract

A water-equivalent fiber-optic dosimeter was fabricated using an organic scintillator, a plastic optical fiber and a photo-multiplier tube for real-time dosimetry in diagnostic radiology. We measured the scintillating lights, which are changed due to the exposure parameters, by using the fiber-optic dosimeter placed on top of the acrylic-aluminum chest phantom to provid a backscatter medium. The light output signals of the fiber-optic dosimeter were compared with entrace surface doses obtained using a dose-area product meter and a semiconductor dosimeter.
