本文报告了一个完整的人的牙齿和它的基础牙本质-釉质交界处使用超声波在10 MHz的范围内的频率进行圆周扫描的结果。图像清楚地显示了牙本质-釉质交界处的二维轮廓，其深度和横向分辨率分别约为100 μ m和750 μ m。所得到的超声波图与同一牙齿的光学显微照片进行比较，以验证超声波技术的准确性。这一结果是朝着牙齿体积内亚毫米尺寸特征的生物定位迈出的重要一步。
This paper reports the results of a complete circumferential scan of a human tooth and its underlying dentino-enamel junction using ultrasound at frequencies in the 10-MHz range. The imagery shows clearly a two-dimensional contour of the dentino-enamel junction with a depth and lateral resolution of approximately 100 mum and 750 mum, respectively. The resulting sonograph is compared with an optical micrograph of the same tooth to verify the accuracy of the ultrasonic technique. The results are a significant step toward the biolocation of submillimeter size features within the tooth volume.
