  This paper describes the development of a novel medical Xray 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 Xrays, 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 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 percent, at 2.34 micro Gray,
even under harsh environments i.e. 60 degrees Celsius and 98 percent humidity.
