Image registration is the problem of finding a coordinate transformation that spatially aligns two or more images. It is a common necessity in applications of medical imaging.

What Is Image Registration? Image registration is an image processing technique used to align multiple scenes into a single integrated image. It helps overcome issues such as image rotation, scale, and skew that are common when overlaying images.

Brain image registration methods can be divided into rigid and non-rigid registration ing to the type of the parameters about spatial transformation [8]. Rigid registration involves only translation and rotation, and is usually used in rigid structures such as skeletons.

Four steps of image registration: top row-feature detection (corners were used as the features in this case). Middle row-feature matching by invariant descriptors (the corresponding pairs are marked by numbers). Bottom left-transform model estimation exploiting the established correspondence.

| The general principle of image registration; a spatial transform V-basically a combination of three-dimensional rotation and translation-is iteratively determined by comparing features in both image datasets (referred to as base and match images in the text).

Examples include registration of brain CT/MRI images or whole body PET/CT images for tumor localization, registration of contrast-enhanced CT images against non-contrast-enhanced CT images for segmentation of specific parts of the anatomy, and registration of ultrasound and CT images for prostate localization in ...
