Abstract

A seven-channel optical fiber radiation dosimeter system has been developed to monitor doses received by patients undergoing radiation therapy. The dosimeter is based on the use of a copper-doped fused quartz material that exhibits optically stimulated luminescence following exposure to a radiation field. The system has been characterized in a clinical setting and found to provide a linear dose response over the entire range of doses that are commonly encountered during external beam radiation therapy.
