✦ Synopsis

We have developed a general-purpose registration algorithm for medical images and volumes. The transformation between images is modeled as locally affine but globally smooth, and explicitly accounts for local and global variations in image intensities. An explicit model of missing data is also incorporated, allowing us to simultaneously segment and register images with partial or missing data. The algorithm is built upon a differential multiscale framework and incorporates the expectation maximization algorithm. We show that this approach is highly effective in registering a range of synthetic and clinical medical images.

Image registration is a very important problem in computer vision and medical image processing. Numerous algorithms for registering single and multi-modal image data have been reported in these areas. Robustness as well as computational efficiency are prime factors of importance in image data regist

A novel automatic registration algorithm for the alignment of medical imaging data was developed. The algorithm measures alignment by comparison of dense feature sets (tissue labels) and optimum alignment is found by minimizing the mismatch of tissue segmentations.

Although intensity-based similarity measures are increasingly used for medical image registration, they often rely on implicit assumptions regarding the imaging physics. This paper clarifies the assumptions on which a number of popular similarity measures rely. After formalizing registration based o
