Improved Myelin Water Fraction Estimation and Uncertainty Mapping in Multicomponent T2 Relaxometry via NNLS Bootstrap Aggregation
Erick J Canales-Rodríguez, Thomas Yu, Juan Manuel Górriz +5
Estimating the myelin water fraction (MWF) from multicomponent T2 relaxometry requires solving an ill-conditioned inverse problem, making estimates sensitive to noise. Regularizati…
