Results from Bloch simulation of the accelerated 3D T1ρ acquisition. a Curve showing the dependence of T1ρ relaxation error on heart rate. b The magnetization response curves showing the transverse magnetizations for TSL = 2 ms and 50 ms, c the fully sampled input image, d the k-space undersampling pattern modulated by the transient magnetization, e The plot of intensities across a horizontal line, (the location is shown using an orange dotted line in Fig. 2c) for the images reconstructed from the undersampled data using inverse Fourier transform (IFT) and using 3D TV constraints. The CS reconstruction has sharper edges as compared to IFT reconstruction. f The plot of estimated T1ρ values across the horizontal line for the T1ρ map estimated from the IFT and 3D CS reconstruction
