Quantitative analysis of the performance of various reconstruction methods applied to imaging of volunteers and patients. Relative root mean square error (rRMSE) and signal-to-noise ratio (SNR) are shown, with error bars indicating one standard deviation. (a) rRMSE of the complex-valued images; (b) Regional rRMSE over the myocardium of the phase images; (c) SNR values. At an acceleration rate of 2, both methods offered similar rRMSE, although BLOSM-SENSE presented higher SNR. At an acceleration rate of 4, BLOSM-SENSE showed significantly lower rRMSE compared to SENSE for complex and phase data (*p < 0.05, ANOVA). BLOSM-SENSE showed significantly higher SNR compared to SENSE reconstruction (*p < 0.05 v.s. SENSE, &p < 0.05 v.s. fully-sampled, ANOVA)
