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...

A Bilevel Sensitivity-Corrected Reconstruction Framework with Deep Priors for Parallel MRI

A model-driven bilevel optimization framework that couples SENSE-based image reconstruction with SPIRiT-based k-space calibration through shared CSMs, and introduces a deep-prior-guided regularization strategy that preserves the structure of classical linear regularizers while adaptively learning spatially varying regu...
