Call for Participant

Accurate automated quantitative estimation of spinal curvature is an important task for the clinical evaluation and treatment planning of Adolescent Idiopathic Scoliosis (AIS). It solves the disadvantage of manual Cobb angle measurement (time-consuming and unreliable) which is the current clinical standard for AIS assessment. A couple of attempts have been made for automated Cobb angle estimation on single-view x-rays. However, it is very challenging to achieve a highly accurate automated estimation of Cobb angles because it is difficult to utilize the information of x-rays efficiently. This, in turn, has sparked specific interest in developing methods for accurate automated spinal curvature estimation and error correction in spinal anterior-posterior x-ray images.[1]

The goal of MICCAI 2019 Challenge on accurate automated spinal curvature estimation and error correction from x-ray images is to investigate (semi-)automatic spinal curvature estimation algorithms and provide a standard evaluation framework with a set of x-ray images. The challenge participating teams (two co-authors in each participating team) will be invited to contribute to a joint journal paper describing and summarizing the challenge outcome, which will be submitted to a high-impact journal in the field. This Challenge is in conjunction and with the support of the 2019 MICCAI Workshop on Computational Methods and Clinical Applications for Spine Imaging.
