In this study, Monte-Carlo simulation was used to optimize the DSI imaging parameters for intersecting crossing fiber mapping. We synthesized diffusion MRI measurements of two crossing fibers. The results showed that DSI could differentiate smaller crossing fibers (&[le] 30 &[deg] ) under clinical gradient limitations with higher b-value encoding. The criteria for DSI parameter selection were also optimized.
