Spatio-Temporal Convolutional LSTMs for Tumor Growth Prediction by Learning 4D Longitudinal Patient Data [article]

Ling Zhang, Le Lu, Xiaosong Wang, Robert M. Zhu, Mohammadhadi Bagheri, Ronald M. Summers, Jianhua Yao
2019 arXiv   pre-print
We extend ConvLSTM into the spatio-temporal domain (ST-ConvLSTM) by jointly learning the inter-slice 3D contexts and the longitudinal or temporal dynamics from multiple patient studies.  ...  However, current 2D patch-based modeling approaches cannot make full use of the spatio-temporal imaging context of the tumor's longitudinal 4D (3D + time) data.  ...  Fig. 2 . 2 Left: The proposed Spatio-Temporal Convolutional LSTM (ST-ConvLSTM, or ST-CLSTM) network for learning of 4D medical imaging representations to predict tumor growth or segment object.  ...
