Frequency-splitting Dynamic MRI Reconstruction using Multi-scale 3D Convolutional Sparse Coding and Automatic Parameter Selection

Dynamic magnetic resonance imaging (MRI), including dynamic contrast-enhanced (DCE) MRI and cardiac MRI, has been widely used to analyze changes in tissue characteristics or the movement of organs over time. Since dynamic MRI ’s diagnostic performance is highly correlated with its temporal resolution (El Khouli et al., 2009), speeding up the acquisition time has been actively studied in the recent decades. More recently, compressed sensing theory (Donoho, 2006) has been applied to the MRI reconstruction problem (Lu stig et al., 2008) to reduce the acquisition time.
