Slicer4:Download Data

Back to Slicer 4 Developer Projects

Introduction

• This is a first generation mock-up for a database display/download schema for Slicer
• The NA-MIC download data can be used for prototyping.
• thumbnails should be extracted for now from the center slice of the volume. Mechanism to replace manually. Down the road, we will use the thumbnail from the mrml file.
• Annotation should be extracted from the DICOM headers, if available. We will need a painless way to edit the annotation (with wiki style history). Once the slicer annotation module is working (summer 2011), we can extract information from there.
• Pack as many thumbnails as possible horizontally (based on width of browser window and font size)
• Only list one or two lines of text, the rest pops up on rollover.
• Pack densly, use space sparingly

Top Level

	Brain: Multi-modality (sMRI, DTI, fMRI) from Schizophrenia Study There are 20 cases: ten are Normal Controls and ten are Schizophrenic. Each case includes a weighted T1 scan, a weighted T2 scan, an fMRI scan, a DTI volume, the DWI with 51 directions, and several masks and labelmaps. Available from Harvard.
	Brain: 2-4 Year Old from Autism Study Data for 2 autistic children and 2 normal controls (male, female) scanned at 2 years with follow up at 4 years from a 1.5T Siemens scanner. Files include structural data, tissue segmentation label map and subcortical structures segmentation. Available from UNC.
	Brain: White Matter Lesions for Lupus Study Data for 5 cases of Lupus White Matter Lesion patients. The data is co-registered. Each case contains: T1-weighted, T2-weighted, FLAIR, and masks for brain and lesions. Available from MIND.
