Description
In order to obtain an image of scattered X-ray in the diagnosis domain, we have newly developed a pin-hole camera. Because of the necessity of the X-ray shielding, the pin-hole part has a depth corresponding to that of the shielded material. As a result, efficiencies of obliquely incident X-rays are reduced. To decrease the descent of the efficiencies, we developed a large camera using a 10×12 inch size phosphor plate as an X-ray detector. A phantom was irradiated by X-rays with conditions of 500 mAs and 5000 mAs, and images of scattered X-rays were obtained. The former image showed scattered X-rays from the phantom. The latter image showed those from the air of beam axis as well as from the phantom. Moreover, we made a new proposal to obtain an optical image using the fading effect.
