Abstract

A method may include providing an initial flip angle schedule of refocusing radio frequency pulses, the refocusing radio frequency pulses being configured to generate an echo train; comparing the initial flip angle schedule with a first criterion, the first criterion relating to a first parameter relating to the echo train; determining, a first flip angle schedule based on the first comparison, the first flip angle schedule satisfying the first criterion; comparing the first flip angle schedule with a second criterion, the second criterion relating to a second parameter relating to the echo train; determining, a second flip angle schedule based on the second comparison, the second flip angle schedule satisfying the second criterion; and obtaining a magnetic resonance (MR) signal based on the second flip angle schedule.
