A new approach is proposed for improving the Partial Fourier reconstruction in asymmetrically collected double echo gradient echo data with two reverse polarity echoes. Comparison is made with conventional Partial Fourier reconstruction (POCS). The high resolution phase estimate obtained using the proposed method, helps POCS converge more efficiently.
