To develop a ground-breaking and cost-effective technology for the direct conversion of X rays into electronic charges by using thick (>500um) semi-conducting hybrid organic inorganic perovskite layers. Two complementary deposition processes, compatible with large area panels, will be implemented
The short-term and low-risk “powder sintering route’ to improve the performance and robustness of the current process and upscale it from small area to 20×20 cm prototype detectors (TRL 5).
The medium term solution process route will have to be developed to obtain much higher optoelectronic performances through denser and higher crystallinity perovskite layers compared to powder sintering, and upscaled to 5×5 cm demonstrators (TRL 4),
To develop direct X-ray imaging detectors based on the hybrid perovskite layers of objective 1, demonstrate breakthrough advances in flat panel detector efficiency and spatial resolution,
To deliver a high-performance photonic imaging system to improve sensitivity, specificity and accuracy, and enhance diagnostics and treatments of two major diseases. CVD and COPD.
More specifically, to validate functional prototypes of perovskite-based X-ray detectors from objective 2 by integrating them in a full-functional cardiac X-ray imaging system, to show enhanced image quality and visibility of small details (moving stents) during interventional CVD treatment, in an state-of-the-art X-ray phase contrast imaging (PCI) system setup, to show advanced diagnosis capability (early detection) for COPD, in clinical settings
To validate a new concept of an X-ray PCI system that operates at 50% lower X-ray dose and without an expensive large-area high-resolution grating, by taking advantage of the advanced perovskite X-ray detector performances to include interleaved electrode fingers in the poets
