bration functions, briefly described as follows:
•
Receptor - Provides for selection of a Receptor/Film Screen for AEC
calibration
•
Optical Density - Calibrates the currently selected Receptor/Film Screen
and ion chamber combination to a user-selectable, base optical density
(gray level) setting. This target level, referred to as the "Base OD
setting", determines the basic "gray-level" quality of images acquired in
AEC mode
