摘要： X-ray imaging systems play an important role in the diagnostic process of various medical conditions. Generating an accurate artificial X-ray image has multiple advantages. It allows for flexible configurations during generation. The resulting images can reduce testing time and cost, help the training of surgeons, and increase the amount of data for artificial intelligence model training. The generation of an X-ray image involves the simulation of a raytracing algorithm through a data model. In this research, a naive approach to this problem is examined. It was found that this approach can be improved by implementing model parallelization, data caching, and data compression. The resulting algorithm is simulated and validated in a software environment. This is then implemented for both an Ultrascale+ and a Versal FPGA. The results show that the algorithm can achieve real-time X-ray image generation, matching the performance of currently used detectors, provided that the required memory performance is achieved.

摘要： Recycled concrete aggregates (RCA) have been recognized as a sustainable solution to satisfy the demand and address the environmental impacts of the concrete industry. However, construction engineers and contractors still have reservations about RCA due to their heterogeneous origin and lower quality compared to natural aggregates. It is essential to know the properties of the parent concrete, in particular its chemical composition, before demolishing concrete structures in order to identify the source of the raw materials. Despite its importance, this has never been done before. This thesis aims to analyze in-situ chemical composition of concrete and to identify the type of cement used in concrete structures by applying the non-destructive characterization technique of a handheld X-ray Fluorescence (hXRF) analyzer. To achieve this, laboratory experiments were performed to assess important factors in measuring cement paste and concrete surface chemical composition using the hXRF. These examined the impact of different water-to-cement (w/c) ratios, curing age, relative humidity, and carbonation on the chemical composition analysis with hXRF, and to gain valuable insights regarding the oxide concentrations of concrete and the most influential factors in hXRF measurements. The results indicated no impact on the chemical composition measurements with the hXRF despite the w/c ratios, the curing age, and carbonation. It was identified that higher relative humidity conditions than 75% affect the measurements with hXRF. Subsequently, three case studies were considered for the in-situ assessment of chemical composition. Conducting tests with hXRF demonstrated the device's potential for analyzing concrete characteristic oxides (MgO, Al2O3, SiO2, SO3, CaO, Fe2O3). As a result, it facilitated cement-type recognition and provided valuable information regarding its opportunities and challenges. Drawing on insights from the literature review, laboratory experiments, and in-situ me
