The objective of this paper is to show what the current techniques in image processing, artificial intelligence, and computer graphics can do in computed tomography. More concretely, we wish to show that given the tomographic data what can be done in order to: a) improve the spatial resolution b) improve the visualisation of the data c) improve the identification of anatomic structures Thus, we shall not deal with different hardware, nor with various reconstruction algorithms. We shall assume that the data is given and ask what can be done from there on. Examples, documenting each of the above points, will be presented.
