To calibrate the sensitivity-band of transition-band SSFP fMRI, a SSFP angle adjustment method based on a sweep scan with increment of SSFP angle has been proved its potential in previous studies. In this study, we proposed a real-time feedback optimization method to calibrate the SSFP angle automatically and rapidly. Through network connection of MRI scanner and an external PC, a feedback loop was created. An optimization method is proposed to search the optimal SSFP angle automatically. The results demonstrate that it exhibits similar effectiveness of the previous sweep scan method and requires much shorter calibration time.
