A review of deep learning-based three-dimensional medical image registration methods

Haonan Xiao, Xinzhi Teng, Chenyang Liu, Tian Li, Ge Ren, Ruijie Yang, Dinggang Shen, Jing Cai
2021 Quantitative Imaging in Medicine and Surgery  
Recently, the successful implementation of deep learning (DL) in various fields has prompted many research groups to apply DL to three-dimensional (3D) medical image registration.  ...  This review summarized the progress made in DL-based 3D image registration over the past 5 years and identify existing challenges and potential avenues for further research.  ...  For example, Haskins et al. used a deep CNN to learn a similarity metric for registration between MR and transrectal US (TRUS) images (79) .  ...

Towards Augmented Reality: MRI-TRUS Fusion for Prostate Cancer Interventions

MOHAMMAD ALI JAN GHASAB
2019
Transrectal ultrasound (TRUS) and magnetic resonance imaging (MRI) are two commonly used medical imaging technologies.  ...  Multimodal image fusion in this fashion would improve the clinical efficacy of image-based guidance for prostate cancer interventions.  ...  non-rigid registration methods, robust point matching (RPM) by Haili et al. [25, 122] and coherent point drift (CPD) by Myronenko et al. [107] appear to be the most frequently used algorithms for non-rigid  ...

Real-time Biomechanical Modeling for Intraoperative Soft Tissue Registration

Stefan Suwelack
2015
In contrast to previous attempts at biomechanically based registration, this novel physics based interpretation allows casting the shape matching problem into a single variational formulation.  ...  This approach treats the non-rigid surface registration as an electrostatic-elastic problem, where an elastic body that is electrically charged (preoperative model) slides into an oppositely charged rigid  ...  In order to use MR based preoperative data in this context, it has to be registered to the TRUS image.  ...
