ABSTRACT:
A method is proposed for reducing the residual artefacts, such as blurring, which occurs in the image when the known methods are used, for example due to phase errors. In accordance with the proposed method, a number of steps are performed per column in the data matrix so as to produce an ever better estimation for the data not known from sampling. After the reconstruction, the image will have a phase which at least approximates the phase estimated from the central part of the data matrix. In the case of phase errors, substantially no residual artefacts will remain and at the same time the signal-to-noise in the image will be superior to that obtained by means of the known methods.
