## Abstract In this paper we continue our studying of the iterative maximum‐likelihood reconstruction method. We consider only the continuous case and show some convergence properties of the algorithm. In the discrete case convergence has already been proved. An example demonstrating divergence of

## Abstract In this work an iterative reconstruction method based on generalized autocalibrating partially parallel acquisitions (GRAPPA) reconstruction is introduced. In the new method the reconstructed lines are used to reestimate and refine the weights from all the acquired data by applying the

In this work, some techniques are proposed to improve the usual Newton-Raphson Method (NRM) used in the numerical analysis of large strain viscoplastic problems. These techniques, based on the ΓΏrst-order perturbation technique, allow to deΓΏne an adaptive step strategy and to improve the trial soluti

Many problems in physics involve imaging objects with high spatial frequency content in a limited amount of time. The limitation of available experimental data leads to the infamous problem of diffraction limited data, which manifests itself by causing ringing in the image. This ringing is due to in

## Abstract In non‐Cartesian SENSE reconstruction based on the conjugate gradient (CG) iteration method, the iteration very often exhibits a β€œsemi‐convergence” behavior, which can be characterized as initial convergence toward the exact solution and later divergence. This phenomenon causes difficul
