Single shot multidimensional imaging using linear and non-linear enocoding fields auch as 4-Dimensional Radial In/Out or North West Echo Planar Imaging allow to combine the preservation the variability of spatial resolution and to avoid the total resolution loss in the center of the field of view. A field camera consisting of 16 field probes is used for trajectory calibration. Analytically derived Maxwell terms of the used PatLoc head insert gradient coil are used to choose an adequate set of basis functions to further improve the image quality.
