Query: A Point Cloud Generative Model via Tree-Structured Graph Convolutions
  for 3D Brain Shape Reconstruction   Fusing medical images and the corresponding 3D shape representation can
provide complementary information and microstructure details to improve the
operational performance and accuracy in brain surgery. However, compared to the
substantial image data, it is almost impossible to obtain the intraoperative 3D
shape information by using physical methods such as sensor scanning, especially
in minimally invasive surgery and robot-guided surgery. In this paper, a
general generative adversarial network (GAN) architecture based on graph
convolutional networks is proposed to reconstruct the 3D point clouds (PCs) of
brains by using one single 2D image, thus relieving the limitation of acquiring
3D shape data during surgery. Specifically, a tree-structured generative
mechanism is constructed to use the latent vector effectively and transfer
features between hidden layers accurately. With the proposed generative model,
a spontaneous image-to-PC conversion is finished in real-time. Competitive
qualitative and quantitative experimental results have been achieved on our
model. In multiple evaluation methods, the proposed model outperforms another
common point cloud generative model PointOutNet.
