A set of X-ray imaging system is introduced. With the application of virtual instrument technology,the image acquisition board is driven by means of Call Library Function Node offered by Labview and the X-ray image signal is processed to display on Labview platform in this X-ray imaging system. With the combination of corresponding hardware components,the radiation perspective image is acquired. The experimental results show the feasibility of this design,realizing the inspection of non-transparent objects. The design makes use of the convenience of Labview graphic programming and the development function of virtual instrument as well as reduces the cost of the system.
