An iterative reconstruction procedure is then performed on the undersampled time series where joint multicoil sparsity is enforced by applying a total\u2010variation constraint along the temporal dimension. Required coil\u2010sensitivity profiles are obtained from the time\u2010averaged data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>iGRASP achieved higher acceleration capability than either parallel imaging or coil\u2010by\u2010coil compressed sensing alone.
