This study focused on developing an automatic gray matter nuclei segmentation method. A 3D convolutional neural network based method was proposed, which adopted patches with different resolutions as input for segmentation. Experimental results showed much higher segmentation accuracy over the atlas-based method and other deep-learning-based methods in terms of both the similarity and the surface distance metrics. The segmentation results of the proposed method is also evaluated in terms of measurement accuracy, where the proposed method achieves the highest consistency with the manual delineations.
