Haptic guided 3-D deformable image registration [PDF]

open access: yesInternational Journal of Computer Assisted Radiology and Surgery, 2009
We present a system which supports deformable image registration guided by a haptic device.The haptic device is tied to a block matching method where a set of uniformly distributed control points determine the block positions. Each control point constitutes a particle in a mass spring grid which limits the space of allowed movements to elastic ...

Prior-based Coregistration and Cosegmentation [PDF]

open access: yes, 2016
We propose a modular and scalable framework for dense coregistration and cosegmentation with two key characteristics: first, we substitute ground truth data with the semantic map output of a classifier; second, we combine this output with population ...

A GPU-Accelerated Deformable Image Registration Algorithm With Applications to Right Ventricular Segmentation

open access: yesIEEE Access, 2017
Delineation of the cardiac right ventricle is essential in generating clinical measurements such as ejection fraction and stroke volume. Given manual segmentation on the first frame, one approach to segment right ventricle from all of the magnetic ...

Adversarial Deformation Regularization for Training Image Registration Neural Networks [PDF]

open access: yes, 2018
We describe an adversarial learning approach to constrain convolutional neural network training for image registration, replacing heuristic smoothness measures of displacement fields often used in these tasks.

Quicksilver: Fast Predictive Image Registration - a Deep Learning Approach [PDF]

open access: yes, 2017
This paper introduces Quicksilver, a fast deformable image registration method. Quicksilver registration for image-pairs works by patch-wise prediction of a deformation model based directly on image appearance.

A Deep Learning Framework for Unsupervised Affine and Deformable Image Registration

open access: yes, 2018
Image registration, the process of aligning two or more images, is the core technique of many (semi-)automatic medical image analysis tasks. Recent studies have shown that deep learning methods, notably convolutional neural networks (ConvNets), can be ...

Registration of brain tumor images using hyper-elastic regularization [PDF]

open access: yes, 2012
In this paper, we present a method to estimate a deformation field between two instances of a brain volume having tumor. The novelties include the assessment of the disease progress by observing the healthy tissue deformation and usage of the Neo ...
