Abstract
A problem of time elongation in image reconstruction due to necessity of many iterations is solved, when an image is reconstructed by performing iterative approximation on measurement data acquired by an MRI apparatus without full-sampling. Density is estimated in the course of the iteration, and density is corrected using thus estimated density. Density estimation is performed not only on initial values but also on every iteration process, thereby enabling convergence with a smaller number of iterations.
