FIG. 3.

Images reconstructed from 2D spiral acquisition data. [(a) and (b)] Image obtained by conventional gridding reconstruction without (a) and with (b) ORC; (c) image obtained after applying standard GNL correction (std. GNLC) to (b); (d) result of the proposed reconstruction method with integrated GNL correction and simultaneous ORC; (e) line profiles across three groups of resolution bars in the images after the standard (c) and the proposed GNL correction (d). The red circles indicate the outer contours of the phantom tracked from the images after GNL correction.
