Abstract
In order to detect parts deformation during industry test, a novel industry computed tomography (ICT) system taking advantage of the rotation of specimens itself was purposed by us. However the rotary motion blur is introduced into the reconstruction image due to the dynamic data acquisition in the system. This article presents a simulation of the data acquisition to analyze the image blurs in the reconstruction and evaluate methods to deblur motion blurred images. Image retrieval algorithms are employed to correct the reconstructed image directly and to correct the projection before reconstruction expecting to suppress the rotary motion blur respectively. Estimation of motion parameters is also included in our work. Furthermore numerical simulations are performed to demonstrate the effectiveness of these methods.
