在我们以前的研究中，我们专注于视频荧光造影（VF）中颈椎的运动，我们发现在正常吞咽过程中生理性脊柱前凸减少。在该研究中，要求在VF的所有帧中手动提取颈椎。因此，本研究难以基于大量患者数据进行统计分析。本研究提出了一种自动跟踪方法的颈椎VF使用的二维模板匹配技术。在该方法中，颈椎可以自动提取，虽然需要手动设置模板，只有在第一帧的VF。自动跟踪方法应用于颈椎，从C1到C6，在实际VF的10例谁计划接受颈椎后路融合术。在Jaccard指数中能够以超过77%的准确度跟踪颈椎。实验结果表明，所提出的方法能够分析吞咽VF中颈椎的运动。
In our previous study, we focused on the motion of cervical spines in video-fluorography (VF), and we revealed that the physiological lordosises were reduced during normal swallowing. In the study, cervical spines were required to be manually extracted in all the frames of VF. Therefore the study had a difficulty in performing the statistical analysis based on a large amount of patient data. The present study proposes an automatic tracking method of cervical spines in VF by use of the two-dimensional template matching technique. In the method, cervical spines can be extracted automatically, though templates should be set manually only in the first frame of VF. The automatic tracking method was applied to cervical spines, from C1 to C6, in actual VF of ten cases who were planned to undergo posterior cervical spinal fusion. The cervical spines were able to be tracked at the accuracy of more than 77% in the Jaccard index. The experimental results demonstrated that the proposed method was able to analyze the motion of cervical spines in VF during swallowing.
