On-line MRI sequences for the evaluation of Apple internal quality

On‐line dynamic MRI requires high‐speed sequences with motion correction artifacts. In this study, two alternative motion corrected sequences are proposed and implemented in real‐time (FLASH and UFLARE), based on T2* or T2 respectively. Sequence selection is related to the expected contrast effect of the disorder: while watercore enhances bright areas due to higher fluid mobility, internal breakdown potentiates low signal due to texture degradation. Metrological aspects such as repeatability of dynamic images and subsequent histogram feature stability become of major interest for further industrial application. Segregation ability among varyin degrees of disorder is also analyzed.
