Research Fields
- My research focuses on the development of low-field MRI technology, with a particular emphasis on improving image reconstruction methods through the use of computer vision, machine learning, and optimization algorithms. Currently, I am simulating the MRI system in a virtual environment, optimizing magnetic field inhomogeneities using advanced computational techniques such as genetic algorithms. The potential application of reinforcement learning is also being explored at this stage. This work combines elements of physics, data analysis, and optimization techniques to fine-tune system performance.
