Comparative study.To compare manual and deep learning-based automated measurement of Cobb angle in adolescent idiopathic scoliosis.We proposed a fully framework to measure the AIS patients. Whole-spine images 500 individuals were collected. 200 digital radiographic (DR) labeled manually as training set, remaining 300 used validate by mean absolute error (MAE), Pearson or spearman correlation coefficients, intra/interclass coefficients (ICCs). The relationship between accuracy vertebral...
