    科学领域:

    • 矯正牙醫和臉外科手術
    • 医疗成像医学成像
    • 机器学习 机器学习

    背景情况:

    • 头脑测量分析对于正牙科和大面部手术至关重要,传统上使用X射线.
    • 缩小视野 (FOV) 圆束计算机断层扫描 (CBCT) 尽量减少辐射,但可能省略关键的骨地标,如 nasion.
    • 准确的药物鉴定对于有效的治疗计划至关重要.

    研究的目的:

    • 研究使用机器学习 (ML) 模型预测骨的位置的可行性.
    • 评估ML模型在从软组织地标估计 nasion 的准确性.
    • 探索一个不那么侵入性的替代头脑测量分析,减少辐射暴露.

    主要方法:

    • 分析了137个CBCT扫描的数据集.
    • 使用软组织标志物 (,Tragus,Alare) 作为预测.
    • 通过10倍交叉验证评估了线性回归,随机森林和前神经网络 (FFNN) 模型.

    主要成果:

    • 线性回归实现了最高的精度,平均欧几里德误差为1.452 ± 1.077毫米.
    • 机器学习模型通过软组织特征可靠地估计了骨标志.
    • 这些发现支持使用ML来预测国家位置.

    结论:

    • 机器学习模型可以从软组织参考准确地预测骨标志,为头脑测量分析提供一种减少辐射的方法.
    • 这种方法可以在没有全 CBCT 的情况下进行 nasion 估计,从而提高安全性,特别是对于儿科和对辐射敏感的患者.
    • 在里程碑式的预测中,进一步开发人工智能可以推进非侵入性面诊断,并改善患者护理.
