Segmentation, in the context of informatics for radiology, refers to the delineation of an areas of interest in imaging in terms of pixels or voxels. Segmentation is often accomplished by computerized algorithms that vary in complexity from simply selecting pixels of similar values in proximity to those that include radiometric features or are based on machine learning. Segmentation is usually a necessary step in creating modifiable three dimensional images for surface modeling and/or medical printing from imaging.
