Events:Registration Summit August 2009

Agenda

• Attendees: Casey Goodlett, Steve Pieper, Dominik Meier, Andriy Fedorov, Ron Kikinis
• Date and place: Friday, August 21, 1249 Boylston, 2nd floor conference room
• Schedule

1. 09:00-12:00 Review of registration in Slicer:
   1. What input is the user asked to provide and in what form.
   2. Does a standard user understand what they are supposed to provide?
   3. What does the user expect registration results to look like?
   4. Bias correction
   5. histogram normalization
   6. handling image distortion (EPI)
   7. capture range and start pose
   8. ROI/VOI
   9. greyscale versus segmentation
   10. List of modules:
       1. transformation module
       2. linear registration
       3. rigid registration
       4. affine registration
       5. b-spline registration
       6. register images
       7. Utah b-spline
       8. mvtk ICP
       9. ACPC registration
2. 12:00-01:00 Lunch
3. 01:00-05:00 Making plans, use case scenarios, sample data sets

Needs

• Robust solutions
• Clinical APIs as opposed to engineering APIs
• Good default parameters
• Modality recorded in the image class to automate use case and parameter selection
• Fast techniques for interactive investigations
• Non-interactive techniques can run longer
• Transform IO to all modules (mapping RAS to LPS as needed)
• Ability to apply estimated transforms to other types of data
• Region of interest registration (anything from a brain mask to a structure segmentation)
• Validation datasets
