| Popis: | The reconstruction of the magnetic resonance images for different levels of the gradient systems instability is considered. The original technique for minimizing the negative effect of deviations of measurement points in K-space on the quality characteristics of reconstructed tomograms is proposed. On the example of real MR image processing limit values of instability parameters are determined taking into account the possibilities of their compensation. It is shown that the construction of several tomograms for different angular positions of transverse magnetic gradient systems with subsequent integration makes it possible to increase their informatively. |
