Design of optical probe for dental computed radiographic system

Abstract

Existing dental radiographic systems have used analog X-ray films. In trend of digital radiography we developed and tested dental computed radiographic system. No image is obtained from prototype dental computed radiographic system, so we analyze the cause of that. And it is believed that photostimulated luminescence from PSP plate is not collected sufficiently. Therefore we developed mathematical model of light collection with solid angle, and calculated light collection efficiency. Prototype has much low light collection efficiency. To acquire image, new light collector is designed and it is believed that new collector has larger light collection efficiency than that of prototype.
