4. Marty, can you create a
Couple of screenshot slides
From the tutorial (showing lines)
And from one case showing
Feedback with green.

8. Study Protocol
Two Phases:
1. Radiograph Calibration
– Remove educationally poor cases
– Broad sample of expertise
– Use Rasch Modelling to ensure appropriate difficulty
2. Actual Trial
– Target Population
