Medical image registration is a typical two-image task which requires specialized feature representation networks for deep-learning-based methods (The existing methods and their limitations have been evaluated in our papers). Therefore, we designed a X-shape feature representation backbone which combines the relationship-aware capacity of Transformer and the traits of two-image tasks which foucus not only on structure information of each image but also on cross correspondence between the image pair. The overall structure of our network is following:

Available implementation

  • MindSpore/ (updating)
  • Pytorch/

★ Notes: implemented under two training strategies VoxelMorph and PC-Reg and the detailed corresponding main functions are Unsup-train.py and Semi-train.py respectively (Pytorch)

Major results from our work

  1. XMorpher has the best DSC score and Jacobian score under both strategies

  1. XMorpher has visual superiority on some detailed structures
