In the field of medical application, it is of great importance to
adopt digital image processing technique. Based on the
characteristics of medical image, we introduced the digital image
processing method to the X-ray imaging system, and developed a
high resolution x-ray medical sequential image acquisition and
processing system that employs image enhancer and CCD. This system
consists of three basic modules, namely sequential image
acquisition, data transfer and system control, and image
processing. Under the control of FPGA (Field Programmable Gate
Array), images acquired by the front-end circuit are transmitted
to a PC through high speed PCI bus, and then optimized by the
image processing program. The software kits, which include PCI
Device Driver and Image Processing Package, are developed with
Visual C++ Language based on Windows OS. In this paper, we present
a general introduction to the principle and the operating
procedure of X-ray Sequential Image Acquisition and Processing
System, with special emphasis on the key issues of the hardware
design. In addition, the context, principle, status quo and the
digitizing trend of X-ray Imaging are explained succinctly.
Finally, the preliminary experimental results are shown to
demonstrate that the system is capable of achieving high quality
X-ray sequential images.
