This paper describes the development of a novel medical X-ray imaging system adapted to the needs and constraints of low and middle-income countries. The developed system is based on an indirect conversion chain: a scintillator plate produces visible light when excited by the X-rays, then a calibrated multi-camera architecture converts the visible light from the scintillator into a set of digital images. The partial images are then unwarped, enhanced and stitched through parallel processing units (FPGA) and a specialized software. All the detector components were carefully selected focusing on optimizing the system's image quality, robustness, cost-effectiveness and capability to work in harsh tropical environments. With this aim, different customized and commercial components were characterized. The resulting detector can generate high quality medical diagnostic images with DQE levels up to 60 % (@ 2.34 µGy), even under harsh environments i.e. 60 ºC and 98% humidity.
