- A
deep learning method was proposed to automatically segment brain nuclei including
caudate nucleus, globus pallidus, putamen, red nucleus, and substantia nigra on
QSM data. The trained network could accurately segment brain nuclei regions.

U-net++. U-net++ consists of an encoder and decoder path that are connected
with nested and dense skip connections.
