Instrument Variables for Reducing Noise in Parallel MRI Reconstruction

Figure 2

The reconstructions (rows (a), (d), (g)), the corresponding zoomed square regions (rows (b), (e), (h)), and difference maps (rows (c), (f), (i)) from scanned in vivo data, in which “Ref.” is reference image, “G” represents GRAPPA, and “P” denotes proposed method, the number at left of “-” represents reduction factor, and the number at right of “-” is the number of ACS lines. Rows (a–c) are the four-channel brain (axial) results; rows (d–f) are the four-channel brain (axial) results; rows (g–i) are the eight-channel brain (axial).
