Framelet Regularized SENSE Calibration in \({k}\)-Space with Conditional Sensitivity-Map Updates for Parallel MRI Reconstruction
Abstract. Parallel Magnetic Resonance Imaging (pMRI) shortens scan time by reducing the amount of k-space data acquired from multiple receiver coils. Conventional model-based reconstruction algorithms typically exploit either coil sensitivity information in the image domain or intercoil correlations in the frequency d...
