Defacing head and neck CT scans while preserving lymph nodes
Key Investigators
- Steve Pieper (Isomics, Inc., USA)
- Ron Kikinis (BWH, USA)
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
- Use generic segmentation tools (CADS, SuperSynth, etc.)
- Identify facial feature landmarks. Find existing models or examples that identify features like corners of eyes and mouth
- Figure out which features can be reliably detected that define a reasonable identity removal but leaving the nodes in the cheeks and jaw
- 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
- Describe specific steps you have actually done.
