From: Improved scan efficiency for golden-angle radial CMR with anisotropic field-of-view
Phantom images. Parameters: 144 spokes, 0.75 mm isotropic resolution, 400 × 120 pixels. a) Conventional GA sampling, b) proposed GA sampling for elliptical FOV (major-to-minor-axis ratio 1:0.3). Note the significantly reduced streaking artifacts in b). The unaliased FOV shapes are also shown (white dashed lines) for each sampling scheme.
