摘要
The invention provides various systems, machine readable programs and methods for performing imaging using a MR scanner. The MR scanner includes at least one local radio- frequency transmit coil and at least one local gradient coil. The local radio-frequency transmit coil(s) and local gradient coil(s) cooperate to define an imaging volume. The MR scanner further includes a control system for performing an imaging operation on a patient's anatomy disposed within the imaging volume. The control system permits a selective simultaneous increase of the gradient magnetic field strength and peak B1 field strength by substantially the same factor, f.
