Julian Wyatt achieves first place in MICCAI Cephalometric Landmark Detection Challenge

DPhil student Julian Wyatt has won a challenge at MICCAI 2024, the International Conference on Medical Image Computing and Computer Assisted Intervention.  

Julian achieved first place in the ‘CL-Detection 2024: Cephalometric Landmark Detection in Lateral X-Ray Images’ international challenge. Candidates were required to develop a model that could detect 53 landmarks on a diverse dataset of 700 Cephalometric x-rays. The challenge assessed both efficiency and accuracy in accordance with real clinical practice. 

Quote from Julian:  I am thrilled that several months of dedicated effort have allowed us to achieve such accurate results. This accomplishment means our model is now better at recognising landmarks in new x-ray domains. The method and results will be published in a paper co-authored with my supervisor Irina Voiculescu. 

Cephalometric analysis 
Cephalometric analysis involves an examination of the dental and skeletal relationships of the human skull. Healthcare professionals such as orthodontists and orthognathic surgeons analyse cephalometric x-rays to study the relationships between bony and soft tissue landmarks to inform treatment decisions. The identification of these craniofacial landmarks is labour-intensive and time-consuming, even when performed by experienced clinicians. Fully automatic accurate landmark localisation can reduce annotation time whilst maintaining quality of care.  

The work was funded by an EPSRC Research Scholarship and used the University’s Advanced Research Computing service.
