Abstract
This paper describes on the general feature of the radiographic imaging, the latest radiography equipment and the technology, radiographic image quality, image processing and future prospects. The radiographic imaging is different than the ordinary imaging in many aspects. One of the major differences is that the wavelength is extremely short (0.05nm). Conventional film and conventional image intensifier are going to be replaced by the latest digital radiography and fluoroscopy system respectively having a flat-panel detector that can display the image immediately after exposure. The x-ray exposure is so limited to show the wave-particle duality due to the dose consideration that some technical concepts such as the detective quantum efficiency in the evaluation of the image, as well as the sensitivity of the detector are required. The digital radiographic equipment has many kind of image processing such as the sensor characteristics correction and the diagnostic processing, then it makes the system to offer the high diagnostic quality images.
