| Here are some cortical (the outer bone surface) thickness measurements over a skull. These can be really useful for trying to predict effects on bone, for instance mechanical forces during a head injury, or how the skull varies with age. The colour shows thickness from 0 to 4 mm, and in this location the cortex is just one layer of bone. | However, in many places the skull has two layers or 'tables'. The apparent discontinuities are where we are suddenly switching between a thickness measurement of both layers, and just the outer layer. This project is about trying to make consistent measurements of either the whole cortex, or of just the inner or outer table. |
