科学领域:

  • 牙科 牙科是指牙科的专业.
  • 医疗成像医学成像
  • 人工智能的人工智能

背景情况:

  • 准确的基底骨宽度评估对于诊断大横向缺陷至关重要.
  • 区分正常闭塞与缺陷有助于治疗规划,包括大扩张.

研究的目的:

  • 评估深度学习 (DL) 模型在测量基底骨宽度方面的有效性.
  • 评估自动化DL测量与手动测量的一致性.

主要方法:

  • 一个基于U-Net的DL模型被开发和训练在80个圆束计算机断层扫描 (CBCT) 图像上.
  • 该模型在10次扫描中得到验证,并在34次扫描中进行测试,测量与手动测量相比,使用一致性相关系数 (CCC).

主要成果:

  • DL模型测量了基底骨宽度,每张CBCT图像大约需要1.5秒.
  • 在DL和手动测量之间发现了很高的一致性 (上宽度为0.96的CCC和下宽度为0.98).
  • 不同测量范围的成功检测率从71.34%到91.18%不等.

结论:

  • 开发的DL框架显著提高了对大宽度评估的诊断准确性.
  • 这种DL模型显示了作为一个有价值的计算机辅助诊断工具在牙矯正的潜力.
