Magnetic Resonance Fingerprinting (MRF) is a fast quantitative MR Imaging technique able to obtain multi-parametric maps with a single acquisition, but data processing is limited by escalating memory and computation needs. Neural Networks (NNs) accelerate reconstruction, but training still requires significant resources. We propose an FPGA-based NN for real-time brain parameter reconstruction from MRF data. After a traditional software validation, the NN is reduced through Quantization Aware Training to meet the available resources of the FPGA hardware accelerator, creating a quantized model that uses lower precision without affecting the NN performance. Training the NN is estimated to take 1000 to 10000 seconds, representing a significant improvement over standard CPU-based training, which can be up to 36 times slower. This approach has the potential to enable real-time brain analysis on mobile devices, potentially revolutionizing clinical decision-making and telemedicine..
