Method for eliminating array CT image distortion

The invention belongs to the technical field of microscopic CT (Computed Tomography) imaging, and particularly relates to a method for eliminating array CT image distortion, which can be used for carrying out gray compensation and distortion correction on defects of current CT imaging. The method for eliminating the distortion of the array CT image is applied to an array CT imaging system. The method for eliminating the distortion of the array CT image comprises the step of obtaining a gray compensation reference formula of the array CT imaging system. And obtaining an image of the calibration plate, performing gray compensation on the image of the calibration plate, and obtaining a distortion elimination characteristic formula of the array CT imaging system. And forming an image of an object to be imaged according to the array CT imaging system, and performing distortion correction on the image of the object to be imaged according to the distortion elimination characteristic formula. And forming an image of
