本文的目的是探讨应用超声技术观察舌形的可能性。超声波技术的优点之一是对人体无害。除此之外，舌头的前部是普通x光照片难以看到的物体。用这种方法观察到的五个日语元音的矢状轮廓与x射线技术观察到的舌状轮廓吻合得很好。舌根周围的前缘轮廓显示，在发/i/、/e/和/o/音时形成了沟槽。对于所有这三个元音，颏舌肌表现出更高的活动。因此，观察到的沟可能代表了颏舌肌的插入部分。由于我们在本研究中使用的仪器是为临床目的而设计和开发的，例如检查甲状腺肿瘤，因此我们获得的数据信息有限，特别是可视化区域较窄。但是，如果我们可以使用扇形孔而不是线性孔，我们可能有更广泛的区域可以观察。用超声波仪器观察舌形是合适的。
The purpose of this paper is to discuss the possibility of application of ultrasonic technique to observe tongue shape. One of the advantages of ultrasonic technique is harmlessness to the human subject. Beside this, the frontal section of the tongue which is the difficult object for ordinary X-ray photo can be visualized. Sagittal contours of the tongue for five Japanese vowels observed by this method are well corresponding to those by X-ray technique. Contours of the frontal section at around the tongue root show a groove formation during /i/, /e/, and /o/ production.For all of these three vowels, the genioglossus muscle shows higher activity. Therefore, the observed groove may be representing the inserting portion of the genioglossus muscle.Since the apparatus we used in this study is designed and developed for the clinical purpose, for example to examine the thyroid tumor, the data we got had limited informations especially, the visualized area was narrow. But if we can use the sector type porbe instead of the linear type, we might have the wider area to be observed.The ultrasonic apparatus would be appropreate for observation of the tongue shape.
