肺炎是日本的第三大死因，其中几例与吸入性肺炎有关。然而，目前尚无吞咽功能评价的定量指标。因此，我们决定使用咽部超声视频建立无创性指标。我们在此提出了一种方法来获得的运动速度和食管的开放条件，以及团的流速，这被认为是有效的指标的食物相对应的吸入。此外，使用该方法，可以通过在吞咽不同粘度的三种液体时提取元素来可视化和比较食管壁和食团的流动特性。
Pneumonia is the third leading cause of death in Japan, several cases of which are associated with aspiration pneumonia. However, no quantitative indicator exists for swallowing function evaluation. Therefore, we decided to use pharyngeal ultrasound video to establish the indicator noninvasively. We herein propose a method to obtain the movement speed and opening condition of the esophagus as well as the flow speed of the bolus, which are considered effective indicators of food-correspondent aspiration. Additionally, using this method, the flow characteristics of the esophageal wall and the bolus can be visualized and compared by extracting the elements at the time of swallowing three liquids of different viscosities.
