Quantification of longitudinal arch curvature in the sagittal plane for a specimen with no pathology (a) and a subject with flat feet (c); quantification of transverse arch curvature through pronosupination angle for a specimen with no pathology (b) and a subject with flat feet (d). The angular values are represented as projected on the plane of view for sake of convenience, however these are spatial angles obtained according to the described parametrization of bone orientation
