The Optimize menu of the Plaque window presently supports two functions:

• Show Exposure Factors - displays % exposure of the source to the optimization reference point if lip or slot collimation is enabled.
• Optimize Carrier Angle... - in this dialog you select an optimization reference point, a plaque to optimize, and rotate the silicone carrier to find the orientation which minimizes dose to the optimization point.
• Lock Carrier Angle - locks the carrier so it can not be accidentally rotated. The carrier can also be locked or unlocked from the Plaque Location... dialog.
