The concept of simultaneous excitation and acquisition (SEA) introduced with the SWIFT technique enables MRI of samples with very short T2 also under B1 constraints. Here, new reconstruction strategies are reported that address the specific encoding scheme of SEA in a general way, providing an exact and flexible reconstruction procedure. Artefact-free SEA images acquired with 50 kHz bandwidth and 10 s echo time are presented.
