The use of subject\u2010specific models allows mapping of the spatial structure and the mineral content of the bone graphically and quantitatively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Subject\u2010specific models and mineral density maps from pig jaws were developed using segmentation, transcription tools and finite element analysis software. This study considered six frozen heads from pigs aged 10\u201312\u2009months, and phantom solutions of K<jats:sub>2<\/jats:sub>HPO<jats:sub>4<\/jats:sub>.

The average percentage error relative to the mineral density maps was \u221218.4%.
