Fast Spatial Resolution Analysis of Quadratic Penalized Least-Squares Image Reconstruction with Separate Real and Imaginary Roughness Penalty: Application to fMRI

Penalized least-squares iterative image reconstruction algorithms used for spatial resolution limited imaging, such as functional magnetic resonance imaging (fMRI), commonly use a quadratic roughness penalty to regularize the reconstructed images. When used for complex-valued images, the conventiona...
