Images of a contrast phantom at R=8 comparing algebraic reconstruction with a sparsity-promoting algebraic reconstruction for O-space, Radial, and a CP-optimized O-space for CS. Optimization meant an acquisition change of modulating the Z2 SEM field strength per TR and using a sparsity promoting reconstruction. Experiments were performed on a 3T Siemens Trio. SENSE is not shown as the reconstruction is intractable due to noise amplification at R=8. Features are better resolved when using pseudo-random CPs compared to regular CPs.
