FOV = CT image field of view; Inter-slice = Distance between CT slice planes.
3D visualizations made using volume rendering, in which each voxel in a data set is assigned a color and an opacity; the latter allows some parts of the specimens to be made transparent, allowing internal features to be viewed.
