Conclusion: An automated landmark extraction method was developed to assess the growth-rates of vertebrae height in children. The results presented can be used as reference data, while our method allows for retrospective analysis of patient data to assess the effects of paediatric radiation therapy on the growth of individual vertebrae.

Keywords: Paediatric, Vertebral Growth Models
