Significant tissue deformation due to breathing motion requires alignment of pre-interventional MRI on real-time interventional US to compensate for the motion. In this work, we present a hybrid framework (conventional and deep learning) for multimodal deformable registration to provide higher accuracy and retain the low latency required for real-time interventions.
