Coronal thin slab MIP of images (full scale and magnified insets) reconstructed from the in vivo 3D-SWIRLS data set. [(a) and (e)] and [(b) and (f)] MIP of images (full scale and magnified insets) reconstructed by conventional gridding reconstruction without [(a) and (e)] and with [(b) and (f)] ORC; [(c) and (g)] MIP of images (full scale and magnified insets) obtained after applying standard GNL correction (std. GNLC) to the gridding reconstruction results with ORC; [(d) and (h)] MIP of images (full scale and magnified insets) reconstructed by the proposed method with integrated GNL correction and simultaneous ORC. The blue arrows in (a)–(d) demonstrate the change of vessel contour in MIP images caused by correction of GNL-induced distortion. The green arrows in (a)–(d) show that the proposed method (d) provides effective off-resonance correction as the standard gridding reconstruction [(b) and (c)]. The red arrows in [(e)–(h)] highlight that the proposed method with integrated GNL correction (h) prevents the blurring caused by standard GNL correction (g) and improves the vessel clarity in corrected image.
