Engineering Of Fluoroscene Screen Based X-Ray Image Capturing Equipment

The engineering of fluoroscene screen based x-ray image capturing equipment has been done. An x-ray machine is a medical diagnoses equipment which can produce anatomical body structure images without carrying out operation In conventional x-ray machine, imaging results are captured by utilizing films. Then the film is developed to get a body organ image so that it can be directly observed by a doctor. This film developing process generally uses chemical substances and it needs times and additional expenses. Beside conventional x-ray machine, now days there are x-ray machines which equipped with solid state base image capturing modules. In this type of x-ray machine, the resulting image is directly converted to digital images. Furthermore this image can be easily processed in computer. But the price of this type of modules are very expensive. Based on the above problems, this activity will be carried will be carried out to develop an x-ray image capturing module which can produce digital image and low production cost. In this activity, it will carry out an engineering of a fluorescence screen-based x-ray image capturing module. This module consists of a fluorescence screen which will convert x-ray to visible ray, a CCD camera, and a control and data acquisition module, and it will be connected to computer as digital image processor. By using this module, resulting images from x-ray machine can be transferred to computer in the form of digital images. Compared to conventional way which using films, the advantages of using this module is more environmental friendly since there is no chemical substances used. furthermore this module can shorten processing time and cost since the resulting image can be produced directly in digital form which can be cheaply and easily displayed or printed. But, in order to be applicable for a medical diagnoses tool, it needs data which show affectivity of this module compared to conventional film. Therefore, in activity besides engineering module and functional test, it also can be carry out performance comparison by means of comparing between resulting images got by this module and film. From the result, it can be concluded that this equipment has not been applicable for medical purposes. The resulting images are not clearer compared to x-ray film images. Therefore it needs more research to increase images intensity before they are captured by camera. The camera being used should capable to be adjust its light intensity reception. (author)
