Project Summary: A vast amount of radiological data is currently considered suboptimal, and is archived without further use due to their poor spatial resolution and sometimes low quality. Subtle indications of early disease stages are also missed for the same reason. The spatial resolution choice is about finding a good balance between image quality, voxel size and acquisition time. This project aims to deliver computational methods  and software tools to increase the resolution of different modalities of magnetic resonance images (MRI) to ensure better brain research, diagnosis and timely treatment strategies.
