...Christopher L.B. Lavelle In view of the dubious scientific validity of traditional cephalometric analyses, the more accurate technique of biorthogonal analysis was used in this study. Developed from D’Arcy Thompson’s transformation grids, this technique showed similar craniofacial shape changes...

...Christopher L.B. Lavelle With the growing appreciation that traditional cephalographic analyses provide data of dubious scientific validity, this study was undertaken to investigate craniofacial growth using the technique of biorthogonal analysis. This specific technique for the analysis of shape...
