Gold standard - Learning tool

An application for the Image Quizzer is to use it as a educational tool. You can have a user contour a lesion on one page and on the following page, display the user's contour along with a pre-defined gold standard.

In the script example below, in order to display both the user's contour and the gold standard together, the gold standard is loaded in as an Image Type = "Segmentation" on the Segmentation layer. The user's contour is redisplayed on the Label layer.

Prep

Download and save Slicer's RECIST dataset as described in the sample data suggested tree structure section.

Suggested folder structure to match script:

.
└─ ImageDatabase/
    └─ ImageVolumes/
        └─ RECIST-Tutorial-Data/
            ├─ 1007-spgr.nrrd
            └─ 1007-spgr.label.nrrd
