Active Research

Novel MRI Pulse Sequence: RoSA

RoSA, Rotating Single Shot Acquisition, is a novel diffusion sequence developed in this lab for high-quality and high-resolution diffusion imaging. It can achieve spatial resolution of 1x1x1 mm3 at imaging acquisition for diffusion while maintaining high signal-to-noise ratio and minimal image distortion.

White Matter Tractography

In the Wu Lab, whole brain white matter tractography is performed using either CAMINO or MRTrix3 open source software. Hybrid Diffusion Imaging technique is used to acquire high angular resolution samples at high b-value diffusion weighting. Crossing fibers are resolved using q-ball reconstruction for fiber orientation distribution function (ODF).

Super resolution track density map

From tractography, investigators in this lab are able to produce submillimeter super resolution map of tack density using MRTrix3 software.
