From: Cardiac cine with ART for radial parallel imaging reconstruction
The PSF of a 128 x 32 Np acquisition, reconstructed with ART using A) 1 coil and B) 8 coils circularly arranged. Images are scaled identically (0 to 10%max) to display artifact pattern and central PSF broadening. In B) note the sharper PSF and reduced streaking. In B) the artifact closest to the central point is least suppressed.
