Study on Industrial CT Algorithm Based on Characteristic Reconstruction

In the industrial CT detection systems,owing to the restrictions of noises such as scattering noise,the traditional methods for CT reconstruction result in the reconstructed image with high noise and low resolution so that they cannot detect small flaws.Relying on the inner structure character of detected object,according to the character of wavelet function before and after RADON transform,the characteristic part of the image is reconstructed by pre-filtering the projected data.The method can protrude the inner small flaw of detected object with the less sacrifice of the resolution of image backgruoud.The method can commendably increase the detect resolution.
