Abstract:
Automatic off-resonance correction for spiral MR imaging is performed in two stages. In the first stage, we acquire a low resolution map using two single shot spirals instead of estimating it using an automatic method. In the second stage, we developed a modified version of automatic off-resonance correction with a frequency constraint from the first stage map.
