Figure 4

Axial brain images reconstructed by GRAPPA(left) and PSVR-GRAPPA (right) under sampling parameters: R = 3 with 24 ACS lines. Both methods were reconstructed in the entire k-space with interpolation windows: 4*3(a), 2*7 (b) and 4*15 (c). Nonaccelerated image is used as reference (top). To the right of each reconstructed image its absolute error with the nonaccelerated image is shown.
