The authors have designed and tested a new compact, very sensitive (< 1 {micro}Rad), X-ray quantum sensor for high energy (0.5--10 MeV) flash imaging. Monte Carlo simulations have been computed for several interesting detector materials (CdZnTe, HgI2-a, BGO, CsI, LSO...). From these calculations, they obtain general design rules and curves which allow one to optimize the pixel size of a sensor to the dose levels. An experimental CdZnTe detector array and its performance is presented.
