Abstract
A CT detector includes a first detector configured to convert radiographic energy to electrical signals representative of energy sensitive radiographic data and a second detector configured to convert radiographic energy to electrical signals representative of energy sensitive radiographic data and positioned to receive x-rays that pass through the first detector. A logic controller is electrically connected to the first detector and the second detector and is configured to receive a logic output signal from the second detector indicative of an amount of a saturation level of the first detector, compare the logic output signal to a threshold value, and output, based on the comparison, electrical signals from the first detector, the second detector, or a combination thereof to an image chain.
