Abstract
A method for calibrating a digital X-ray detector executed at least in part by a control logic processor. A radiation sensor is disposed along the optical path that extends between a radiation emitter and the digital X-ray detector. A set of radiation beam conditions for X-ray generation is selected and digital image values from the digital X-ray detector are obtained in one or more iterations of providing a threshold signal to radiation control logic, the threshold signal corresponding to a predetermined exposure level, exposing both the digital X-ray detector and the radiation sensor to radiation and terminating the exposure according to a comparison of the threshold signal with a signal from the radiation sensor that indicates an accumulated radiation level, then obtaining the digital image values from the digital X-ray detector. One or more sets of calibration values are generated according to the obtained digital image values.
