Gaussian primitives for deformable image registration

open access: yesPhysics and Imaging in Radiation Oncology
Background and Purpose:: Deformable image registration (DIR) plays a critical role in radiotherapy by compensating for anatomical deformations. However, existing iterative and data-driven methods are often hindered by computational inefficiency or ...

Edge-Aware Pyramidal Deformable Network for Unsupervised Registration of Brain MR Images

open access: yesFrontiers in Neuroscience, 2021
Deformable image registration is of essential important for clinical diagnosis, treatment planning, and surgical navigation. However, most existing registration solutions require separate rigid alignment before deformable registration, and may not well ...

Natural gradients for deformable registration [PDF]

open access: yes2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2010
We apply the concept of natural gradients to deformable registration. The motivation stems from the lack of physical interpretation for gradients of image-based difference measures. The main idea is to endow the space of deformations with a distance metric which reflects the variation of the difference measure between two deformations.

Learning a Deformable Registration Pyramid

open access: yes, 2021
We introduce an end-to-end unsupervised (or weakly supervised) image registration method that blends conventional medical image registration with contemporary deep learning techniques from computer vision. Our method downsamples both the fixed and the moving images into multiple feature map levels where a displacement field is estimated at each level ...

Groupwise Registration for Magnetic Resonance Image Based on Variational Inference

open access: yesChinese Journal of Magnetic Resonance, 2022
To address the low precision of pairwise registration method based on the deep learning and the time-consuming nature of traditional registration algorithm, this paper presents a method of unsupervised end-to-end groupwise registration based on ...

Dense Registration with Deformation Priors [PDF]

open access: yes, 2009
In this paper we propose a novel approach to define task-driven regularization constraints in deformable image registration using learned deformation priors. Our method consists of representing deformation through a set of control points and an interpolation strategy. Then, using a training set of images and the corresponding deformations we seek for a

Preliminary Feasibility Study of Imaging Registration Between Supine and Prone Breast CT in Breast Cancer Radiotherapy Using Residual Recursive Cascaded Networks

open access: yesIEEE Access, 2021
Breast cancer is one of the most common malignancies in women. The prone position in Partial Breast Irradiation (PBI) can better protect the heart and lung during radiotherapy. Supine position is used for CT imaging during treatment planning. The posture
