An international research team has determined the key design parameters for manufacturing curved X-ray detectors that can produce better quality and safer X-rays. In recent years, digital flat-panel detectors have enabled radiographers to examine X-rays faster than older photographic films, thereby speeding up diagnosis. However, the flat panel is not suitable for the complex shape and geometry of the human body. According to the research team led by the University of Surrey, the reliance on flat panels means that the edges of images will inevitably be distorted. The tablet can also prevent accurate recording of the delivered X-ray dose, which is a key feature for safer radiotherapy and minimizing secondary tumors. So far, due to the brittle nature of rigid inorganic semiconductors used to manufacture flexible detectors, efforts to manufacture flexible detectors have not been successful. Some curvature has been achieved by using thinner semiconductor layers, but this affects performance levels and results in poor image quality. The new research, published in Advanced Science, determines the design rules for a special class of "organic-inorganic" semiconductors. This work was done in collaboration with the University of Bologna, the National Physics Laboratory, and the University of Sheffield. It explained that by adjusting the molecular weight of bismuth oxide nanoparticles sensitized organic semiconductors to extend the polymer chain, researchers can pave the way for more powerful curved digital detectors with high sensitivity or digital film. The study’s lead author and PhD student at the University of Surrey Prabodhi Nanayakkara said: “Our curved detector concept shows excellent mechanical robustness and enables the bending radius to be as small as 1.3 mm.” “The reason for the need for expensive crystal growth methods Compared to traditional inorganic semiconductors made of silicon or germanium, it is also more cost-effective to use organic or'inorganic in organic' semiconductors. Our approach may provide significant commercial advantages." Ravi, Director of the Surrey Institute of Advanced Technology Professor Silva said that the technology will help create a "revolutionary" high-sensitivity X-ray detector, which is scalable due to the design and materials used. "This technology has great potential in medical applications and other X-ray applications, so we are collaborating with a spin-off company, SilverRay, and hope to turn this technology into the X-ray detector of choice to achieve high sensitivity and high resolution. High-speed, flexible and large-area detector."
