Voxels

Volume Data | | Trilinear Interpolation

In a cartesian grid, that is uniform in all dimensions, all edges of a voxel are equally sized. For a regular grid, the edge length can be different for different axis.

In clinical practice we most often have to deal with the latter, because the distance of cross sections is different from the resolution of the image plane.
