Schematic for a single iteration of the B1-weighted LOST algorithm used in this study. At every iteration, the current image estimate is mapped to individual coil images by voxel-wise multiplication with sensitivity maps. Data consistency is enforced by replacing the acquired k-space lines. A combined image is generated by summing the voxel-wise product of data-consistent coil images and conjugate of coil sensitivity maps across the coil dimension. This image is then thresholded using LOST. The implementation details of LOST thresholding are given in the Appendix.
