The aim of the present study was to introduce and validate an open workflow for the cephalometric evaluation of 2D cephalometric lateral radiographs (FRS) generated from digital volume tomography (CBCT).
This study was performed on four patients with FRS and CBCT with sufficiently large FOV available at the same time. Using a Phyton script written for this project, 2D FRS images were reconstructed from the CBCTs. Each image was cephalometrically analysed by 6 raters. The agreement of the cephalometric values from both methods was checked using Bland-Altman analysis.
Using an open workflow, it was possible in all cases to generate a 2D reconstruction that was sufficient for cephalometric evaluation. The cephalometric analyses performed with this workflow led to clinically comparable results.
The presented open workflow could be validated on the present patient collective.
