摘要
本文提出了一种基于不可分离MRA的小波重建算法。算法将投影数据进行二通道的小波分解,在分解抽样中,使用不同的抽样方法。算法结果,相比通常所使用的基于可分离MRA的小波重建算法基本相同的局部重建特性,重建质量和运算速度都优于后者。
A wavelet reconstruction algorithm based on non-separable MRA has been proposed. In the algorithm the projection data were disposed with two channel wavelet. This algorithm not only has the same local reconstruction characteristics with the algorithm based on separable MRA, hut have better image quality and can he obtained by shorter working time.
