NGWAFOR & PARTNERS SARL, The House of Gideon, Golf/Bastos Quarter, Opposite The American Embassy, Entrance-St. John Paul II Boulevard, P.O. Box 8211, YAOUNDE (CM). (57) Single-sided MRI scanners, systems, and methods are disclosed. A method can include applying a first sweeping frequency pulse defining an X axis; applying a second sweeping frequency pulse defining a Y axis; applying a third sweeping frequency pulse defining the Y axis; and applying a fourth sweeping frequency pulse defines a -X axis. The sweep rate of the fourth sweeping frequency pulse can be less than the sweep rate of the third and/or second sweeping frequency pulse. The sweeping frequency pulses can be chirp pulses. Frequency sweep DEFT pulse sequences can provide the benefits of a broader bandwidth and less sensitivity to the inhomogeneity of a single-sided MRI scanner.
