Validation of nonrigid image registration using finite-element methods: application to breast MR images. [PDF]

, 2003
This paper presents a novel method for validation of nonrigid medical image registration. This method is based on the simulation of physically plausible, biomechanical tissue deformations using finite-element methods. Applying a range of displacements to

Non-Rigid Registration for Infrared and Visible Images via Gaussian Weighted Shape Context and Enhanced Affine Transformation

IEEE Access, 2020
Image registration is a prerequisite for image fusion from multiple modalities, such as infrared (IR) and visible (VIS) images. Although there have been many various methods of image registration, non-rigid registration for IR and VIS images is still ...

Non-rigid registration of medical images based on S 2 1 Δ mn 2 $$ {S}_2^1\left({\Delta}_{mn}^{(2)}\right) $$ non-tensor product B-spline

Visual Computing for Industry, Biomedicine, and Art, 2022
In this study, a non-tensor product B-spline algorithm is applied to the search space of the registration process, and a new method of image non-rigid registration is proposed.

Fast free-form deformation using graphics processing units [PDF]

, 2010
A large number of algorithms have been developed to perform non-rigid registration and it is a tool commonly used in medical image analysis. The Free-Form Deformation algorithm is a well-established technique, but is extremely time consuming.

ROI-Based Intraoperative MR-CT Registration for Image-Guided Multimode Tumor Ablation Therapy in Hepatic Malignant Tumors

IEEE Access, 2020
Image-guided ablation therapy has been widely used as a minimally invasive treatment for hepatic malignant tumors. Image registration is very useful during such operations, especially for multimode tumor ablation therapy.

Neural network-assisted automated image registration for MRI-guided adaptive brachytherapy in cervical cancer

Zeitschrift für Medizinische Physik, 2022
Purpose: In image-guided adaptive brachytherapy (IGABT) a quantitative evaluation of the dosimetric changes between fractions due to anatomical variations, can be implemented via rigid registration of images from subsequent fractions based on the ...

Statistical Motion Mask and Sliding Registration [PDF]

, 2018
Accurate registration of images depicting respiratory motion, e.g. 4DCT or 4DMR, can be challenging due to sliding motion that occurs between the chest wall and organs within the pleural sac (lungs, mediastinum, liver).

Robust Rigid Shape Registration Method Using a Level Set Formulation

, 2010
This paper presents a fast algorithm for robust registration of shapes implicitly represented by signed distance functions(SDF). The proposed algorithm aims to recover the transformation parameters( scaling, rotation, and translation) by minimizing the ...

3D statistical shape models of human bones : their construction using a finite element registration algorithm, formulation on Hilbert spaces, and application to medical image analysis [PDF]

, 2011
Statistical shape models have become a widely used tool in computer vision and medical image analysis. They are constructed from a representative set of example shapes and represent the normal shape variations of a class of objects, in our case of human
