Presently, the movement toward home medical care service is increasing in order to maintain the Quality of Life of the Japanese aged society. The Japanese Ministry of Health and Welfare has permitted medical staffs performing X-ray photography in home medical care if required.However, taking a photograph is very difficult with a conventional system. Because the taken image cannot be checked on that spot unless and until it bring to the hospital. Therefore in this study, we proposed a preview system, which supports X-ray photography by a conventional film/screen system or an imaging plate system. This system is composed by X-ray intensifying screen and an array of CdS sensor. The optical resistance unit is piled up under the X-ray film cassette and use the X-ray penetrated by the cassette. The optical resistance array is composed with 30 CdS in its row and 30 CdS in the column that set on a 35cm X 35cm cassette. As our proposed system is integrated into the conventional X-ray film cassette, it neither generates additional expose, nor increases additional workload for taking photographs. As a fundamental study, we have investigated electrical and optical properties as well as measured penetrated intensity of the X-ray. The result showed good characteristic suggesting high possibility of its clinical use.
