Spherical mean diffusion-weighted images. Spherical mean diffusion-weighted images for magnitude-valued (rows a, b) and real-valued (rows c, d) diffusion MRI data for each diffusion time (Δ) and diffusion-encoding gradient strength of a representative healthy participant. The images are windowed individually for improved visualization, between 0 and a higher image intensity listed at the bottom right of each sub-figure.
