论文摘要
长骨的解剖轴是指导骨折减少并有助于在骨科和创伤手术中正确放置引导销，螺钉和植入物的重要参考线。这项研究研究了一种基于骨骼分割轮廓的X射线图像上此类轴的自动方法。为此，我们使用医学上建立的两行方法并将其转化为基于学习的方法。在38个股骨和胫骨骨的临床测试图像上评估了所提出的方法，并分别达到0.19°和0.33°的中间角度误差。一项与三名创伤手术专家的评价者间研究证实了该方法的可靠性，并建议进一步临床应用。
The anatomical axis of long bones is an important reference line for guiding fracture reduction and assisting in the correct placement of guide pins, screws, and implants in orthopedics and trauma surgery. This study investigates an automatic approach for detection of such axes on X-ray images based on the segmentation contour of the bone. For this purpose, we use the medically established two-line method and translate it into a learning-based approach. The proposed method is evaluated on 38 clinical test images of the femoral and tibial bone and achieves a median angulation error of 0.19° and 0.33° respectively. An inter-rater study with three trauma surgery experts confirms reliability of the method and recommends further clinical application.
