摘要

青少年特发性脊柱侧凸(AIS)是一种在青少年中普遍存在的潜在疾病。早期发现和筛查对于预防畸形的发展至关重要。目前脊柱曲度的评估方法依赖于x射线成像来测量Cobb角和检测脊柱侧凸。然而,辐射暴露限制了它在广泛筛查中的应用。现有的工具既耗时又依赖于医生的专业知识。本研究提出了一种基于深度信息和高阶曲率计算的人体背部不对称评估新方法,旨在对AIS进行无害、准确的快速评估。该方法利用来自后点云的三维曲率的不对称性来评估脊柱侧凸引起的畸形程度。它通过量化左右曲率之间的不对称指数来实现这一点,然后使用这些指数来预测Cobb角并从棘突重建脊柱中线。不同程度Cobb角患者的实验结果显示,x线图像上脊柱中线与重建脊柱中线高度对齐,不对称指数与Cobb角呈显著正相关,Pearson相关系数为0.892。此外,基于该方法建立的筛查系统在涉及2000多名受试者的学校筛查中取得了超过0.95的准确率,强调了其大规模临床应用的潜力。

Intelligent Adolescent Idiopathic Scoliosis Detection Method Based on Three-Dimensional Measurements
Adolescent Idiopathic Scoliosis (AIS) is a prevalent latent disorder among adolescents. Early detection and screening are crucial for preventing the progression of deformities. Current assessment methods for spinal curvature rely on X-ray imaging to measure the Cobb angle and detect scoliosis. However, radiation exposure limits its use for widespread screening. Existing tools are time-consuming and rely on physician expertise. This study introduces a novel method based on depth information and high-order curvature calculations to assess asymmetries in the human back, aiming for a harmless and accurate rapid evaluation of AIS. The method utilizes asymmetries in three-dimensional curvatures derived from back point clouds to assess the degree of deformity caused by scoliosis. It achieves this by quantifying the asymmetry index between left and right curvatures, then using these indices to predict the Cobb angle and reconstruct the spinal midline from the spinous processes. Experimental results on patients with varying degrees of Cobb angles show that the spinal midline on X-ray images is highly aligned with the reconstructed spinal midline, and the asymmetry index is significantly positively correlated with the Cobb angle, with a Pearson correlation coefficient of 0.892. Additionally, a screening system built upon this method achieved an accuracy rate of over 0.95 in school screenings involving more than 2,000 subjects, underscoring its potential for large-scale clinical applications.
