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

Schiz-thumb.png 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.

Child-i.png 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.

Lupus-i.png 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.

How to link a template to a resource

First, go resource edit page:

Midas-slicer-screenshot-link0.jpg

Then select the template you want to use:

Midas-slicer-screenshot-link1.jpg

You can recursively apply the template. (All the children of the resource will use the selected template)

How to upload new files

First, go a collection page and create an item:

Midas-slicer-screenshot-upload0.jpg

Click on "Upload Files":

Midas-slicer-screenshot-upload1.jpg

Select the files you want to upload (you can select multiple files)

Midas-slicer-screenshot-upload2.jpg

If Midas warns you that a file is too big, use the "large files" tool:

Midas-slicer-screenshot-upload4.jpg

When your files are uploaded, you can ask midas to create resources. If you do that, Midas will analyze the selected files and try to find the metadata:

How to change a thumbnail

First, go the an item page:

Midas-slicer-screenshot2bis.jpg

Then go a the menu and click on "thumbnails":

Midas-slicer-screenshot4.jpg

Select the thumbnail you want to change:

Midas-slicer-screenshot3.jpg

Upload a new image (the application will resize the image)

Midas-slicer-screenshot5.jpg

If you like the new thumbnail, click on "Set thumbnail" to finalize the modification
