A growing interest has been observed in energy sensitive pixel array for high flux X-ray imaging. These devices provide compositional analysis of the imaged objects and would be useful in a wide range of applications in the field of security, non-destructive testing and medical imaging. We have developed a CdTe linear array pixel detector for energy sensitive X-ray imaging that can operate at several million counts per second. It is coupled to a novel read circuit that continuously digitizes the signal from each pixel. A FPGA is used process transient signals induced by X-rays, measuring their amplitudes and reconstruct pulse-height spectra in real time.
