In a method and system for echo planar imaging, after having applied a radiofrequency pulse and a slice selection gradient, continuous readout gradients alternating between positive and negative are applied and a phase encoding gradient is applied before starting each readout gradient. A slice selection gradient is applied at the same time as applying the phase encoding gradient. Scanning signals are collected during the duration of the readout gradients. Image reconstruction is implemented based on the scanning signals to obtain a scanned image.
