What is it about?
Improving Intravoxel Incoherent Motion (IVIM) imaging for better measurements about perfusion in human body. We use simulations with general linear model and Cramér-Rao Lower Bounds techniques to find acquisition parameter which provide smallest standard deviation into perfusion parameter maps.

Why is it important?
Based on thorough analysis for acquisition parameters, we suggest optimal b-values to be used in brain IVIM. We make comparison of between various suggested b-value settings for IVIM, using permutations of 16 b-values during 1-hour long scanning session with four volunteers. We found that physiological noise at low b-values and thermal noise at high b-values propagates to parameter maps.
