coregistration

coregistration

(kō-rĕj″ĭ-strā′shŭn)
The correlation of anatomical and metabolic data from different imaging techniques (e.g., from a CT scan and a PET scan of the same organ) in order to obtain enhanced images of diseased tissues.

For anatomic correlation, 0.6-mm isotropic three-dimensional fast imaging employing steady-state images were acquired for coregistration with the functional diffusion-tensor maps.
Despite the lack of a written record, a careful coregistration of modern cartography with the map suggests that knowledge of the Australian continent was carried back to Europe in the early part of the 16th Century, nearly 80 years before the Dutch explorers arrived.
Preprocessing steps included image realignment, slice acquisition-time correction, and functional and anatomical image coregistration. Functional images were normalized to Montreal Neurological Institute's (MNI) template by fitting mean functional images to the single reference EPI standard SPM template, and smoothed with a 6 mm Gaussian kernel to reduce spatial noise.
This includes both the astronomical calculations to relate the scene to the instrument, as well as heuristical calculations to correct errors beyond the spacecraft instrumentation accuracy and achieve pixel-to-coordinate accuracy, as well as pixel-to-pixel coregistration between images on different filters.

The coregistration of PET and CT was visually inspected using PMOD (PMOD Technologies Ltd., Switzerland).
Therefore, image coregistration has become crucial both for qualitative visual assessment and for quantitative multiparametric analysis in research applications.

In the following procedures, coregistration and conormalization of pre- and postimages were avoided for the same reasons as described previously [10].
