Besides several other factors, radiometric differences between a reference and a floating image greatly influence the achievable accuracy of image registration. In this work we derive the magnitude of registration inaccuracy coming from changes in radiometric properties. This is done for the example of medical X-ray image registration. We therefore estimate the change of image intensity with respect to object shape, X-ray attenuation of the object material and the initial X-ray energy by…

A protocol for evaluation of similarity measures for rigid registration
TLDR
The proposed evaluation protocol is useful for selecting the best similarity measure and corresponding optimization method for a particular application, as well as for studying the influence of sampling, interpolation, histogram bin size, partial image overlap, and image degradation, such as noise, intensity inhomogeneity, and geometrical distortions on the behavior of a similarity measure.
Maximum distance-gradient for robust image registration
TLDR
This paper designs a novel spatial feature field, namely the maximum distance-gradient (MDG) vector field, for registration tasks, which encodes both the local edge information and globally defined spatial information related to the intensity difference, the distance, and the direction of a voxel to a MDG source point.
Multimodality image registration by maximization of mutual information
TLDR
The results demonstrate that subvoxel accuracy with respect to the stereotactic reference solution can be achieved completely automatically and without any prior segmentation, feature extraction, or other preprocessing steps which makes this method very well suited for clinical applications.
High-Accuracy Subpixel Image Registration Based on Phase-Only Correlation
TLDR
A technique to improve registration performance by fitting the closed-form analytical model of the correlation peak to actual two-dimensional numerical data and modifying cross-phase spectrum with some weighting functions to enhance registration accuracy is proposed.
Reconstruction and registration of multispectral x-ray images for reliable alignment correction in radiation treatment devices
TLDR
This work presents a method that reconstructs multi-spectral DRRs for different X-ray settings, which can be registered to real X- Raytracing images and shows that higher reliability can be achieved compared to conventional approaches.
Multimodal image registration using floating regressors in the joint intensity scatter plot
TLDR
A new approach for multimodal medical image registration is presented and compares it to normalized mutual information (NMI) and the correlation ratio (CR) and is shown to be comparable to (if not superior to) state-of-the-art implementations of NMI and CR in both accuracy and convergence robustness.
X-ray imaging physics for nuclear medicine technologists. Part 2: X-ray interactions and image formation.
TLDR
The principles of x-ray interactions and image formation are discussed, in preparation for a general review of CT and a more detailed investigation of PET/CT scanners in part 4.
