Journal ArticleDOI
elastix : A Toolbox for Intensity-Based Medical Image Registration
TL;DR: The software consists of a collection of algorithms that are commonly used to solve medical image registration problems, and allows the user to quickly configure, test, and compare different registration methods for a specific application.
Journal ArticleDOI
Fast parallel image registration on CPU and GPU for diagnostic classification of Alzheimer's disease.
Denis P Shamonin,Esther E. Bron,Boudewijn P. F. Lelieveldt,Marion Smits,Stefan Klein,Marius Staring +5 more
TL;DR: The accelerated registration tool elastix is employed in a study on diagnostic classification of Alzheimer's disease and cognitively normal controls based on T1-weighted MRI and has nearly identical results to the non-optimized version.
Journal ArticleDOI
Evaluation of Optimization Methods for Nonrigid Medical Image Registration Using Mutual Information and B-Splines
TL;DR: This work compares the performance of eight optimization methods: gradient descent, quasi-Newton, nonlinear conjugate gradient, Kiefer-Wolfowitz, simultaneous perturbation, Robbins-Monro, and evolution strategy, and shows that the Robbins- Monro method is the best choice in most applications.

TL;DR: The organization of the challenge, the data and evaluation methods and the outcome of the initial launch with 20 algorithms, which comprised the comprehensive evaluation and comparison of 20 individual algorithms from leading academic and industrial research groups are detailed.
Journal ArticleDOI
Automatic segmentation of the prostate in 3D MR images by atlas matching using localized mutual information.
Stefan Klein,Uulke A. van der Heide,Irene M. Lips,Marco van Vulpen,Marius Staring,Josien P. W. Pluim +5 more
TL;DR: An automatic method for delineating the prostate in three-dimensional magnetic resonance scans is presented, based on nonrigid registration of a set of prelabeled atlas images, and the segmentation quality is especially good at the prostate-rectum interface.
