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.
