Validation of the proposed distortion correction scheme employed for the MR-thermometry images. Example of a coronal (left) and a sagittal (middle) MR-thermometry magnitude image acquired on the phantom (a), (b): before and (c), (d): after distortion correction. (e): Extent of the geometric distortions measured for the grid points marked with “x” in a and b, before (left boxplot) and after (right boxplot) correction
