Axial (horizontal) slices taken at 1mm intervals during scanning.
These are put together to produce a three dimensional model in a process called volume rendering.
Low resolution or a degree of noise is common in CT scanning where a balance needs to be struck between radiation dose and quality. Therefore it is often necessary to edit serial slices by hand to pick out the finer details. 3D slicer does help, with features which allow you to watershed some of your selections into adjacent slices.
