Abstract
Automatic exposure control for an x-ray system using a large area solid state x-ray detector includes an array of photodiodes located behind the x-ray image detector to measure photons passing therethrough. The resulting currents from selective ones of these photodiodes are combined to provide a signal used to control the x-ray exposure.
