AbstractThis research suggests the way to automatically calculate Cobb angles from spine X-ray image. Convolutional neural network predicts landmarks, the coordinates of each vertebrae in the image. Spinal curve is extracted by the predicted landmarks by a mathematical algorithm. The network was trained with 609 publicly accessible spine x-ray images. This research achieved SMAPE score of 21.70 on test set, 19.58 on test set with appropriate cropping.

1. Introduction
Adolescent Idiopathic Scoliosis (AIS) is a condition appearing in late childhood or adolescence, characterized by an abnormal curvature of spine. Cobb angle is clinical standard for diagnosis and treatment of AIS, so accurate prediction of Cobb angle is critical. However, manual Cobb angle measurement is time-consuming and prone to errors. Hence, Automatic Cobb angle estimation has been considerably called for to overcome deficiencies of traditional method. [2]
