Upgrading ordinary film machine for DR I. Introduction DR excellent image quality, high efficiency, simple interface features undoubtedly many hospitals radiology digital, networked, filmless and paperless by urgent needs. However, most of the hospital to buy a DR and ordinary radiation X-ray film, CR dispensed it is a pity that some hospitals on the DR's prices are prohibitive. To this end, Keya launch regular medical radiography machine upgrade for DR solutions, to "make full use of existing equipment, with a minimal investment, to expand its capabilities to reach DR possess the function" principle, to meet the majority of users demand. Second, Keya DR features an upgrade, the existing machine to achieve a comprehensive upgrade of film from the function and appearance. 2, to provide medical special resolution CCD detectors or amorphous silicon (selenium) three kinds of flat-panel detector rehabilitation programs for users to choose. 3, DR image acquisition workstation using a unique electronic circuit device to automatically obtain high voltage generator X-ray exposure time to instruct Exposure Timing control imaging detector activation and shutdown. 4, the digital image in 3-5 seconds (CCD 1 second) within the automatic optimization processing fast imaging and post-treatment operations, printing and storage. 5, equipped with high-definition imaging diagnostic workstation. Third, supporting programs of classic luxury mechanical combination of all-electric suspension system - Column fully electric multifunction photography frame U-arm multifunctional intelligent PRO arm perfect choice CCD detector detector detector amorphous amorphous selenium detector
