Scatter corrections
Gold Backing B(r)
- accounts for loss of backscatter that might have originated from behind the plaque, and low energy flourescence emitted from the face of the plaque, that results from the near complete absorption of all primary emissions that were directed towards the plaque shell.
Air Interface A(R)
- accounts for a small reduction in backscatter originating from the air in front of the eye compared to an infinite water environment.
