Core 3 Presentations
9:30 B&W/Harvard Marek Kubicki, Core 3 Talk. Slides. Stochastic Tractography
Additional discussion:
- Slicer3 release date? Some question regarding proper handling of coordinate frames in Slicer3.
- Discussion of registration and existing/needed tools in Slicer 3. Discussion postponed to registration session.
- Discussion re bias field correction and EM seg -> perhaps moreCore3/Core1 interaction needed
9:50 Queen's U not here yet -> talk postponed
9:50 UNC Rachel Smith talk. Slides. Longitudinal study of brain devel. in autism. Additional discussion:
- Brief discussion of segmentation methods for brain substructure segmentations
- Additional clarification/specifics of the status of the processing of datasets
- Status of Marcel segmentation modules and issues re Core2/1 interaction issues -> Utah (Guido, Marcel) waiting for resolution of some critical Core2 software infrastructure issues e.g. chaining infrastructure design before
they can finalize tools
- Cortical thickness measurment algorithms-> Advantages/drawbacks of different methods. Guido: we should compare methods and see difference in simpler vs. more complex algorithms. Martin: Core 3 intends to look at this issue
- Cortical correspondence-> Martin gives update on local correspondence methods status (particle method with freesurfer preprocessing). Issue: Freesurfer not working for pediatric data. Critical Freesurfer functionality will be reimplemented as NAMIC tool
10:20 break
Jeremy Bockholt (DPB lupus)
- collecting new data/ ongoing clinical study (old data)
- discussion about how DTI sequences are selected
- discussion about analysis of lesion growth and identification in follow up images
- ability to find follow up lesions
- growth may merge lesions. lesions may disappear. not expected for lesions to move
- question to test - does lesion information correlate with clinical measures/outcomes
- Discussion of classification comparison for lesions
- Comment on the MICCAI workshop on MS lesions segmentation
- Discussion on methods for segmentation comparison
- Discussion of commercial tool JIM
Core 1 Presentations
John Melonakos & Yi Gao (segmentation)
- prostate segmentation (Yi Gao)
- Extraction of concave valley of prostate for use as landmark in registration
- Discussion of comparison to UNC work (Steve Pizer's group) on prostate segmentation
- 3D Ultrasound (raw vs reconstructed)
- lesion segmentation (John Melonakos)
