Machine Learning in Magnetic Resonance Image Reconstruction and Analysis

Dr. Chen Qin

【摘要】

Machine Learning has shown great potential in improving the entire medical imaging workflow, from image acquisition and reconstruction, to disease diagnosis and treatment. This talk will mainly discuss about the recent advances of deep learning in medical imaging, and particularly focus on our recent achievements in magenetic resonance image (MRI) reconstruction and analysis. Firstly, I will introduce the model-based deep learning research on acceleratred dynamic MRI reconstruction, and discuss about its application to dynamic cardiac MRI cine imaging. Then, I will focus on medical image analysis methods with limited supervision, including the weakly-supervised image segmentation, self-/unsupervised mono-/multi-modal image registration, and biomechanics-informed learning for myocardial motion tracking. Lastly, I will briefly talk about the integration of MRI reconstruction and analysis, which can potentially facilitate the fast and personalized MRI imaging and analysis.
