Project Description

Objective

• Radiologist sometimes would like to make an annotation on an existing CT/MRI/US image. 3D Slicer contains a module to create different kind of annotations.
• The focus of this project is to store annotations created in 3D Slicer in XNAT. XNAT (http://xnat.org) is a framework for storing image (derived) data.
• The annotations should be downloadable in the XNAT webinterface.
• It should be possible to store a description accompanied with the annotation.
• The annotations should be downloadable and viewable in 3D Slicer.
• The interface should not only support DICOM, but also NIFTI and other relevant image filetypes.

Approach, Plan

• Extend or build a module upon the existing XNATSlicer module (https://github.com/skumar221/XNATSlicer) of Sunil Kumar.
• Use custom variables in XNAT to store the description (and possibly other relevant information).

Progress

• Approach 1: Store annotation files only.
• Approach 2: Store mrb file without image. Advantages: 1)more generic as is can include other meta-data, 2) all in one file, 3) prevents duplicate image data.
• Started implementing approach 2) but encountered some problems which have to be discussed with Sunil.
