In hyperpolarized 3He MRI, a flip angle calibration is necessary especially in case of using no-tune coils. A new calibration method based on the analysis of the phase image following a Spatial Modulation of Magnetization preparation (SPAMM) is presented in this work. It has the advantage of being free of error due to the T1 relaxation decay cause by oxygen and does not require image processing with external software but uses the standard commercial scanner interface tool and a simple calculator.
