Abstract: A method and apparatus correcting errors associated with timing offsets in radiofrequency coils. The method and apparatus include a memory element and a controller. The controller is configured to execute a set of instructions to receive data of a plurality of signals, the plurality of signals comprising at least one projection echo. The controller is also configured to identify a plurality of offsets of the plurality of signals based on the at least one projection echo. The controller is also configured to apply the plurality of offsets to a k-space of the plurality of signals.
