Haofu Liao, Yucheng Tang, Gareth Funka-Lea, Jiebo Luo, Shaohua Kevin Zhou
2018 Lecture Notes in Computer Science  
However, it is a challenge to build an automatic contouring algorithm because ICE is noisy and provides only a limited 2D view of the 3D anatomy.  ...  Experimental results show that our model is significantly better than a direct 2D image-to-image deep neural network segmentation, especially for less-observed structures.  ...  It uses 3D geometry and cross-modality appearance knowledge for better anatomical understanding and structural consistency.  ...
