| Research Abstract |
Interventional radiology is increasingly being adopted in the treatment of various diseases because of its low invasiveness. However, the entrance skin doses (ESDs) exceed several Gy for each procedure in most cases. We therefore built a system for precise mapping of ESDs using a number of radiophotoluminescence glass dosimeters to reduce the dose of patient. We also concluded that the precise dose mapping accompanied by monitoring of angiographic parameters during the procedure should contribute to reducing X-ray dose accumulation.
