초록

The film scanner that digitizes the conventional x-ray films is the necessary equipment in the transition period of going to the filmless hospital. We have developed the film scanner using laser. We have selected HeNe laser as light source. The polygonal mirror converts the point light source to line scanning light. In sensing part, the diffusing cylinder and 7 photo transistors converts the light signal which passing the film into the electric signal. With this scanner, we can scan successfully the conventional x-ray film by $1024\times1024$. Smaller the spot sire is, higher the resolution can be achieved.
