Overview of Harvard PNL DBP 1

The Harvard Driving Biological Project uses structural MRI, diffusion-weighted MRI, and fMRI to study the neural bases of schizophrenia and related psychiatric disorders. The DBP is centered in the Psychiatry Neuroimaging Laboratory (PNL) at Brigham and Women's Hospital in Boston, MA.

For more information about the PNL, please visit the lab website.

Diffusion Tensor Image Processing Tools

We implement the diffusion weighted image (DWI) registration model from the paper of G.K.Rohde et al. Patient head motion and eddy currents distortion cause artifacts in maps of diffusion parameters computer from DWI. This model corrects these two distortions at the same time including brightness correction.

New: We have recently developed software for eddy current correction.
