  • 构建包含600张图像、38个标志点的多中心数据集,推动自动化检测研究
  • 顶尖模型平均检测率达75.7%,平均径向误差仅1.518毫米,接近人工水平
  • 揭示当前方法仍存局限,适合医学影像与深度学习交叉研究者参考

从侧位头影测量片中定位颅面标志点是头影测量分析的基础任务。过去几十年间,该任务的自动化一直是研究热点。本文提出“颅面标志点检测(CL-Detection)”数据集,这是目前公开可用且最全面的颅面标志点检测数据集。该多中心、多厂商数据集包含来自三家医疗中心的600张侧位X光片,共标注38个标志点,使用不同设备采集。本文旨在评估当前最先进的深度学习方法在该任务上的表现。基于2023年MICCAI CL-Detection挑战赛结果,报告了前十名研究团队的性能。结果显示,最佳方法已非常接近专家分析水平,平均检测率为75.719%,平均径向误差为1.518毫米。尽管仍有提升空间,但这些成果无疑为高精度、全自动颅面标志点定位打开了大门。同时,本文也识别出深度学习方法仍存在失效场景。数据集及详细结果均已公开,平台将持续开放,供社区未来算法评测:https://cl-detection2023.grand-challenge.org/。

原文摘要 · Abstract (English)

Localization of the craniofacial landmarks from lateral cephalograms is a fundamental task in cephalometric analysis. The automation of the corresponding tasks has thus been the subject of intense research over the past decades. In this paper, we introduce the "Cephalometric Landmark Detection (CL-Detection)" dataset, which is the largest publicly available and comprehensive dataset for cephalometric landmark detection. This multi-center and multi-vendor dataset includes 600 lateral X-ray images with 38 landmarks acquired with different equipment from three medical centers. The overarching objective of this paper is to measure how far state-of-the-art deep learning methods can go for cephalometric landmark detection. Following the 2023 MICCAI CL-Detection Challenge, we report the results of the top ten research groups using deep learning methods. Results show that the best methods closely approximate the expert analysis, achieving a mean detection rate of 75.719% and a mean radial error of 1.518 mm. While there is room for improvement, these findings undeniably open the door to highly accurate and fully automatic location of craniofacial landmarks. We also identify scenarios for which deep learning methods are still failing. Both the dataset and detailed results are publicly available online, while the platform will remain open for the community to benchmark future algorithm developments at https://cl-detection2023.grand-challenge.org/.
