吞咽的视频荧光镜检查仍然是评估吞咽投诉患者的标准。尽管已尝试客观化研究的各个方面，但研究结果在很大程度上是主观的，依赖于临床医生的培训和判断，导致相当大的评估者间变异性。我们描述了一个计算机化的图像分析程序，旨在客观化的一个组成部分的吞咽研究，舌骨的运动。吞咽困难患者与非吞咽困难患者的舌骨运动不同。舌骨抬高降低也被认为是误吸的一个风险因素;然而，在实际量化舌骨运动并将其与吞咽研究的其他方面联系起来方面，还没有做太多的工作。提示临床医生在校准框架中定义舌骨，然后系统在研究的其余部分中跟踪该感兴趣区域。该系统显示出与手动分析的强相关性，并且可以解释研究期间的头部位置变化。虽然在本研究中报告了舌骨，但也可以使用该技术跟踪图像视野内的其他感兴趣区域。像这样的定量分析有机会提高测试的评分者间可靠性，从而使吞咽研究的结果更加一致。
Videofluoroscopic examination of swallowing remains the standard for evaluation of patients with swallowing complaints. Although attempts have been made to objectify aspects of the study, findings from the study are largely subjective and reliant on clinician training and judgment leading to considerable inter-rater variability. We describe a computerized image analysis program designed to objectify one component of the swallow study, the movement of the hyoid bone. Hyoid motion has been shown to be different in dysphagic versus non-dysphagic patients. Reduced hyoid elevation is also considered a risk factor for aspiration; however, there has not been much work done on actually quantifying hyoid motion and associating it with other aspects of the swallow study. The clinician is prompted to define the hyoid bone in a calibration frame, and the system then tracks that region of interest throughout the rest of the study. This system shows strong correlations with manual analysis and can account for head position changes during the study. While the hyoid bone was reported on in this study, other regions of interest within the image field could also be tracked using this technique. A more quantitative analysis such as this has the opportunity to improve the inter-rater reliability of the test and therefore lead to more consistent findings from swallow studies.
