* '''Diffusion measures along fiber tracts of the cingulum bundle'''
** We are trying to obtain diffusion measures (FA, trace, etc.) along fiber tracts of the cingulum bundle, comparing schizophrenic patients with control subjects.
** Participants:
*** MIT: CF Westin, Lauren O'Donnell, Raul San Jose
*** PNL: Marc Neithammer, Sylvain Bouix, Marek Kubicki, Mark Dreusicke
* '''Clustering of anatomically distinct fiber tracts'''
** Lauren O'Donnell (LMI) has developed a method to cluster fiber tracts based on their location and the regions they connect
** Participants:
*** MIT: Lauren O'Donnell, CF Westin
*** PNL: Marek Kubicki, Mark Dreusicke, Martha Shenton
* '''FA/trace measurements of the corpus callosum and anterior commissure'''
** Using ROI labelmaps drawn on sagittally acquired DTI data (higher resolution in sagittal plane), we are calculating diffusion measures in the corpus callosum and anterior commissure of schizophrenic patients.
** This project has involved the coregistration of sagittal and coronal tensor data.
** Fiber tracking (and clustering) is currently being applied to these cases
** Participants:
*** MIT: Lauren O'Donnell, CF Westin, Scott Hoge
*** PNL: Marek Kubicki, Mark Dreusicke

== Progress ==

* [[DBP:Harvard:Software:Testing:DTI:Slicer|'''Software Testing''']]<nowiki>: Scalar measure outputs from the DTMRI module of Slicer (FA and trace) are being compared with standard protocol measurements. </nowiki>
* [[DBP:Harvard:Software:Bugs:2ROI|'''Fiber tracking using multiple ROIs''']]<nowiki>: We are testing the use of multiple ROIs to identify fiber tracts of interest. </nowiki>
* [[DBP:Harvard:Software:Wish:Cluster_3-29-05|'''Fiber clustering''']]<nowiki>: A unique method has been developed to cluster fiber tracts based on their anatomical connectivity. </nowiki>
* [[DBP:Harvard:Software:Wish:3T_8-24-05|'''High resolution DTI acquisition''']]<nowiki>: We are experimenting with the fiber tracking of higher resolution DTI scans. </nowiki>
* [[DBP:Harvard:Software:Wish:Granted:Coregistration_3-29-05|'''Coregistration of sagittal/coronal DTI''']]<nowiki>: To use ROI labelmaps drawn on sagittally acquired data, we have developed a method to coregister the tensors of sagittal and coronal scans, so that labelmaps can be applied to full-brain coronal DTI acquisitions. </nowiki>
* [[DBP:Harvard:Software:Bugs:Solved:DICOM_3-21-05|'''DICOM files''']]<nowiki>: We have ensured that DICOM DTI images are able to read in the Slicer. </nowiki>
* [[DBP:Harvard:Software:Bugs:VolumeMath_3-21-05|'''Masking FA/trace maps''']]<nowiki>: Because of file type incompatability, scalar volumes from the DTMRI module could not be masked with ROI labelmaps. The problem has since been solved. </nowiki>
