Fig. 2From: Semi-automated brain tumor segmentation on multi-parametric MRI using regularized non-negative matrix factorization First row: coregistered MP-MRI maps of a GBM patient, left to right: T1C, FLAIR, rCBV, ADC. Second row, left to right: NMF abundance maps for active tumor, necrosis and edema. The final segmentation masks are shown on the right for active tumor (red), necrosis (yellow) and edema (blue)Back to article page
