Magnetic resonance imaging (MRI) is a highly versatile and widely applied imaging technique. However, data acquisition in the clinical scan is often time-consuming, which compromises the diagnostic value and economic efficiency. Although parallel imaging has been applied routinely to accelerate data acquisition, it so far requires coil calibration for image reconstruction that inevitably prolongs MRI scans. In addition, datasets generally exhibit strong correlations in routine multi-contrast or multi-slice MRI that have rarely been considered. This talk will give an overview of our developed structured low-rank reconstruction technique, with applications to highly undersampled multi-modality MRI. A joint calibrationless reconstruction framework was designed to explore data correlations in multi-contrast or multi-slice MRI and achieve higher acceleration beyond independent reconstruction. During developing this method, a novel data acquisition strategy and deep learning guided reconstruction have also been incorporated to further enhance its robustness.
