Image Noise Covariance Can be Adjusted by a Noise Weighted Filtered Backprojection Algorithm
It was believed that the noise covariance of an image reconstructed with the filtered backprojection (FBP) algorithm is anisotropic. This paper shows that the noise-weighted FBP algorithm is able to alter the noise covariance and make it approximately isotropic. For the noise-weighted FBP algorithm,...
