Volume rendering — is a technique used to display a 2D projection of a 3D discretely sampled data set.A typical 3D data set is a group of 2D slice images acquired by a CT or MRI scanner.Usually these are acquired in a regular pattern (e.g., one slice every… … Wikipedia
Length — is the long dimension of any object. The length of a thing is the distance between its ends, its linear extent as measured from end to end. This may be distinguished from height, which is vertical extent, and width or breadth, which are the… … Wikipedia
