Oscillating gradient spin echo (OGSE) experiments offers
new insight in tissue microstructure by probing
diffusion processes on ultra-short time scales. In this
study we examine different possibilities for sampling
OGSE on anisotropic tissue. We find that the best
results for very limited gradient strength is achieved
with square/trapezoidal gradients in 6 gradients,
whereas a circularly polarized OGSE (CP-OGSE) perform
better at higher gradient strengths. Our results
emphasize that the optimal solution is highly dependent
on the given limitations and the parameters of interest.
