Ultrasonic Scans of the Tongue [PDF]
The Journal of the Acoustical Society of America, 1971 Ultrasonic scans taken along the longitudinal dimension of the tongue, depicting a saggital plane on the dorsal surface of the tongue, are compared with similar views obtained via conventional lateral head x ray. Also, transverse ultrasonic scans are presented which picture the dorsal surface of the tongue in coronal section, coronal oblique section ...
