Aiming at the problem that the spontaneous/involuntary movement of patient＇ s head often results in blurring of CT image in the process of computed tomography （CT） imaging

an image deblurring method for head CT slice image based on the motion blurring theory was excogitated. Before the restoration processing

the motion parameters of head movement were calculated according to motion artifact in head CT slice

establishing the Point Spread Function（PSF） model; finally using Lucy-Richardson algorithm to restore the head CT slice image com- bined with the corresponding PSF model in order to generate clear head CT slice image. Experimental results show that the sharpness of the organization and the outline in the head CT motion blurred image increased in different de- grees after being restored with this method

which has good visual effects.
