| Outline of Final Research Achievements |
Interventional radiology (IVR) is a medical subspecialty of radiology to realize image-guided surgical procedures using imaging modalities, such as x-ray fluoroscopy. However, skin injuries by prolonged x-ray exposure during the procedure have been reported. Therefore, real-time monitoring of skin dose is desired in clinical sites for reduction of excessive x-ray exposure. We developed a real-time dose distribution monitoring system using an organic photodiode directly fabricated on a plastic scintillator for the IVR. The organic photodiode is mainly composed of organic materials, which has good transparency for X-ray. In evaluation with a small animal CT, we obtained the sufficient signals from the OPD in real-time with 1 s interval. In addition, the OPD detector have a transparency enough to be used in the IVR procedure.
