To address these challenges and the lack of interpretability found in certain existing automated methods, we have created fully automated software that not only precisely measures the Cobb angle but also provides clear visualizations of these measurements.

The final image classification model, trained using both manually labeled and pseudo-labeled data, had the higher weighted average AUC (WAUC: 0. 903) value and higher AUC-ROC values among all classes (normal AUC-ROC: 0. 894; abnormal AUC-ROC: 0. 896, arthroplasty AUC-ROC: 0. 990) compared to the baseline model (WAUC=0. 857; normal AUC-ROC: 0. 842; abnormal AUC-ROC: 0. 848, arthroplasty AUC-ROC: 0. 987), trained using only manually labeled data.

Three-dimensional segmentation in magnetic resonance images (MRI), which reflects the true shape of the objects, is challenging since high-resolution isotropic MRIs are rare and typical MRIs are anisotropic, with the out-of-plane dimension having a much lower resolution.
