The composite LF-NMR image reveals distinct internal moisture distribution patterns. The top-left section shows a concentrated region of lower signal intensity near the core, surrounded by higher intensity areas indicating uniform moisture distribution. The top-right section exhibits a more homogeneous signal intensity with slight variations. The bottom sections display a granular texture with varying signal intensities, suggesting differences in tissue structure. The patch morphology appears irregular, with scattered areas of differing moisture content throughout the samples.
