【Abstract】 This paper develops a type of x-ray unit which can produce x-ray image suitable for medical diagnosis. The unit is composed of a CCD image sensor with high sensitivity and high resolution, a digital image acquisition board, and a suit of computer software. The software can be applied as the doctor’s workstation with the functions of patient register, image process and image management. Some styles of digital radiography technology are introduced briefly, and the principle of the x-ray unit as well as its hardware and software designs are presented particularly.更多还原
