Project Description

For the Lymph Node Quantification project we want to analyze and share head and neck scans but don't want to share PHI.

Objective

1. Use generic segmentation tools (CADS, SuperSynth, etc.)
2. Identify facial feature landmarks. Find existing models or examples that identify features like corners of eyes and mouth
3. Figure out which features can be reliably detected that define a reasonable identity removal but leaving the nodes in the cheeks and jaw
4. Decide what bluring or removal to do in the identified face area

Approach and Plan

• Figure out if existing MR defacing tools can be used for this, perhaps by mapping the CT to MR

Progress and Next Steps

1. Describe specific steps you have actually done.
