GOUHFI: a novel contrast- and resolution-agnostic segmentation tool for Ultra-High Field MRI

Marc-Antoine Fortin, Anne Louise Kristoffersen, Michael Staff Larsen +3

Recently, Ultra-High Field MRI (UHF-MRI) has become more available and one of the best tools to study the brain. One common step in quantitative neuroimaging is to segment the brai…
