A linear array ultra-fast scanning x-ray imaging device. The linear array x-ray imaging device is single photon sensitive, operates in frame output mode and includes a pixel array Application Specific Integrated Circuit including the readout pixel array and on the same ASIC there is also provided digital control logic and sufficient digital memory to accumulate digital output frames in various modes of operation prior to output from the ASIC. In this way a number of advanced imaging functionalities are achieved directly on the ASIC such as static frame modulation, dynamic frame modulation and time delay integration output, while maintaining a very large dynamic range of 16 bits and single photon sensitivity. Furthermore, the effective or secondary frames that are 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 object to be imaged. This enables dual energy imaging and ultra-fast scanning, without the complexity and cost of conventional photon counting x-ray imaging sensors. The system architecture is simpler and achieves optimal imaging performance.
