Outline of Final Research Achievements

We proposed a real-time dose distribution monitoring system for Interventional radiology (IVR). Scintillation detectors which consist of low stopping power materials, such as plastic scintillators, are placed on a stretchable cap which can be worn by the patient. Scintillation light is fed to photo detectors outside the FOV through plastic optical fibers. This arrangement means that there are only radiolucent materials in the FOV and the proposed dose monitor does not interfere with the IVR procedure. As a result, the proposed monitor realizes real-time monitoring of the dose distribution on the patient’s skin. We are developing a prototype of the proposed system which consists of three X-ray detectors. We conducted evaluation experiments of detector performance with the micro CT apparatus operating in the projection mode. The experimental results indicated that the proposed dose monitoring system could measure real-time dose distribution with at least a 1 s interval.
