A two-tensor compartment model was used to simulate simple partial volume effects, and the data generated was used to compare the performance of different DTI acquisition schemes in estimating ADC and FA. Results show that the use of multiple b-values increases the accuracy of the measurements, as well as their stability in the presence of noise. Simulations and experimental data also show that the ability to differentiate between tissue types increases with the number of b-values used.
