The creation of x-ray image detector for the installation of digital radiography is considered. The aim of the work is to design X-ray image detector with active area of about 100x100 mm. In order to reduce the dose load on detector electronic components, optical decoupling based on a mirror and a scintillation screen spaced apart in space is used. The calculation of detector optical scheme is carried out and necessary parameters of digital camera and focusing lens are determined. Three-dimensional CAD model of the detector was developed and an experimental model was made. Techniques for the experimental determination of parameters and characteristics of the detector are given. Basic spatial resolution of the detector is determined, the value of signal-to-noise ratio of images is estimated, and modulation transfer functions are constructed
Key words: : digital X-ray detector, microfocus X-ray tomography, digital radigraphy, CMOS camera, basic spatial resolution, modulation transfer function.
