| Abstract | Echo planar imaging (EPI) has been used in many applications such as fMRI and DWI. However, EPI images are prone to Nyquist ghost and geometric distortion.In this study, we proposed a new scheme based on reversed readout strategy to correct both Nyquist ghost and geometric distortion artifacts on EPI images simultaneously. We have demonstrated the proposed method can effectively remove Nyquist ghost and correct geometric distortion both in phantom and rat brain. This method may be paticularly suited for dynamic EPI protocols such as fMRI and dynamic contrast-enhanced MRI applications. |
