A comparison of similarity measures for use in 2-D-3-D medical image registration
TLDR
Results show that the introduction of soft-tissue structures and interventional instruments into the phantom image can have a large effect on the performance of some similarity measures previously applied to 2-D-3-D image registration. Expand
Multi-scale line segmentation with automatic estimation of width, contrast and tangential direction in 2D and 3D medical images
TLDR
A new multi-scale segmentation technique for line-like structures in 2D and 3D medical images is presented, based on normalized first and second derivatives and on the eigenvector analysis of the hessian matrix, which allows for the estimation of the local diameter, the longitudinal direction and the contrast of the vessel.

Landmark-based elastic registration using approximating thin-plate splines
TLDR
The authors consider elastic image registration based on a set of corresponding anatomical point landmarks and approximating thin-plate splines and uses a semi-automatic approach based on three-dimensional (3-D) differential operators to localize landmarks. Expand
A reliable and fast method for the solution of Fredhol integral equations of the first kind based on Tikhonov regularization
In many physical and chemical applications one is faced with the problem of calculating the solution of a Fredholm integral equation of the first kind from noisy experimental data. For such problemsExpand
Automatic Model-Based Segmentation of the Heart in CT Images
TLDR
The model-based approach for the fully automatic segmentation of the whole heart (four chambers, myocardium, and great vessels) from 3-D CT images shows better interphase and interpatient shape variability characterization than commonly used principal component analysis. Expand
Voxel-based 2-D/3-D registration of fluoroscopy images and CT scans for image-guided surgery
TLDR
A novel voxel-based method in combination with a new similarity measure (pattern intensity) has been developed for registration of intraoperative fluoroscopy images with preoperative 3D CT images, and the results for a spine phantom are presented and discussed. Expand
A nonlinear regularization method for the calculation of relaxation spectra
It is well known that the relaxation spectrum characterizing the linear viscoelastic properties of a polymer melt or solution is not directly accessible by an experiment. Therefore, it must beExpand
Determination of the relaxation spectrum by a regularization method
La determination du spectre de relaxation a partir des donnees d'ecoulement cisaille oscillatoire de faible amplitude en utilisant une regression lineaire n'etant pas satisfaisante utilisation d'uneExpand
Benchmark for Algorithms Segmenting the Left Atrium From 3D CT and MRI Datasets
TLDR
A standardisation framework can be used to label and further analyse anatomical regions of the LA by performing the standardisation directly on the left atrial surface, including meshes exported from different electroanatomical mapping systems. Expand
Point-Based Elastic Registration of Medical Image Data Using Approximating Thin-Plate Splines
TLDR
This study considers elastic registration of medical image data based on thin-plate splines using a set of corresponding anatomical point landmarks using an approximation scheme based on regularization theory to lead to a more accurate and robust registration result. Expand
