High-resolution X-ray Medical Sequential Image Acquisition and Processing System Based on PCI

The high-resolution X- ray medical sequential image acquisition & processing system, which adopted image amplifier and CCD to digitize X-ray medical sequential image was described. The system was composed of three modules, which were sequential image acquisition, data transport and image processing. With its good performance in data transport, PCI interface was used to transport data. The images acquired by hardware were transported to PC through PCI bus and then, were optimized by the image processing software. Software kits, which include PCI device driver and image processing package, were developed with visual C++6.0 language. The running principle and procedure of X-ray sequential image acquisition & processing system is given. The emphasis is the key problems of PCI device driver program based on Windows OS. In addition, the context, principle, status and the digitizing trend of X-ray imaging are given briefly.
