RAPID THREE-DIMENSIONAL MAGNETIC RESONANCE TAGGING FOR STUDYING MATERIAL DEFORMATION AND STRAIN

摘要

A method for producing an image of a selected region of interest included in a volume within a moving and deforming object in a Magnetic Resonance Imaging (MRI) system includes applying at least one integrated preparatory pulse sequence to the region of interest prior to any subsequent imaging sequences. The integrated preparatory pulse sequence is adapted to simultaneously alter longitudinal magnetization of spins located outside of the selected regionand to further impose a grid pattern on the selected region. Th e integrated preparatory pulse sequence is subsquently followed by a projection imaging technique.
