Abstract
A method of shimming a magnetic field, includes applying radio frequency (RF) signals to an object, using a transceiver coil, and calibrating phase offsets of magnetic resonance signals acquired from the object through a receiver coil. The method further includes generating RF signals to be applied through the transceiver coil based on magnetic resonance signals acquired from the object through the transceiver coil and the calibrated magnetic resonance signals.
