Abstract :
We propose a wavelet reconstruction algorithm based on non-separable MRA. In the algorithm we disposed the projection data with two channel wavelet. This algorithm not only has the same local reconstruction characteristic with the algorithm based on separable MRA, but have better image quality and shorter working time.
