The fast development of the Graphics Processing Unit’s programmability and parallel computing power provides new solutions for visualization technology. Using Image processing techniques according to the ICT image gray state of existence and CUDA based classical ray-casting algorithm of volume rendering，By the contrast of volume rendering’s effect showed in different aspects involved in its entirety，plane cutting and local amplification;We can get high quality image with fast speed and with the preprocessed volume date used in the method Contrast finely with the original volume date, which can be well complementary to display the characteristics of defects.
