Disclosed is a linear array ultra-fast scanning x-ray imaging device. The linear array x-ray imaging device is single photon sensitive, operating in frame output mode and including a pixel array Application Specific Integrated Circuit including the readout pixel array. The ASIC includes digital control logic and sufficient memory to accumulate digital output frames in various modes of operation prior to output from the ASIC, permitting advanced imaging functionalities directly on the ASIC, while maintaining a dynamic range of 16 bits and single photon sensitivity. The effective or secondary frames output from the pixel array ASIC can be tagged with user provided external triggers synchronizing the effective frames to the x-ray beam energy and/or to the movement of the x-ray source or imaged object. This enables dual energy imaging and ultra-fast scanning, without complex and costly conventional photon counting x-ray imaging sensors. The system architecture is simpler and higher performance.
