Temporal reconstruction of sonographic imaging of disturbed tongue movements.

Documentation of tongue movement during swallowing has been restricted to the recording of fluorographic or ultrasound images on cine- or videofilm. The new approach of temporal sonographic imaging with reconstruction of one single image for the total act of swallowing presents a direct approach to obtaining substantial information concerning tongue movements and motility. The applicability of this reconstructed image for the documentation, interpretation, and comparison of tongue movements is demonstrated using examples of normal and pathologic swallowing.

[Ultrasonography of the tongue in the rehabilitation of speech articulation disorders].

There has been presented a possibility of application of ultrasound examination of the tongue in the diagnosis and phoniatric rehabilitation exemplified by exposing shapes of the lateral surface of the tongue during correct articulation of the Polish vowels and articulatory exercises in the system of visual feedback in a normally hearing child and in a deaf one.

[Computerized ultrasound imaging of the shape of the tongue in forming long vowels in German].

The contours of the tongue during pronunciation of the long German vowels were assessed by ultrasound in 22 healthy volunteers. Using statistical methods, models of the shape of tongue were calculated. These models can be used for clinical diagnosis and bio-feedback therapy in patients with speech disorders.

[Magnetic resonance tomography and sonography during articulation].

The use of MRI for demonstrating the articulators during phonation by means of a snapshot-FLASH technique has been studied in ten healthy subjects. Unlike ultrasound, which can only demonstrate movement of the tongue during articulation, MRI with snapshot-flash technique provides significant information on all articulators during phonation.

[Ultrasound sonography of active and passive tongue motility].

Applying both B- and M-mode sonography, we examined tongue movements during swallowing, during repetitions of identical and changing syllables and during continuous articulation of voiced apical /r/. A pseudo-three-dimensional reconstruction was developed for tongue movements registered in B-mode. Our approach can be easily applied for the evaluation of impaired tongue motility in speech pathology.

[Computerized sonographic imaging of tongue motility using pseudo-3 dimensional reconstruction].

A new method for analysis and documentation of tongue movements was used in 24 healthy volunteers. This method enables direct digitalization of the information obtained from sequences of B-Mode pictures. Besides of allowing to further digital evaluation of the findings, it offers the facility of "pseudo 3D"-reconstruction of the tongue movements occurring on swallowing. The method appears to be of particular value for therapy control in neurological and phoniatric patients.

[Ultrasonic diagnosis of the pseudoglottis in laryngectomized patients].

The validity of ultrasonic imaging as a tool for the investigation of pseudoglottal movements was studied in five good to excellent esophageal speakers. The length of pseudoglottis and vibration rate during phonation of vowels was evaluated by means of B-mode and M-mode sonography respectively. The pseudoglottal vibration rate as seen in M-mode sonography was in high agreement with the fundamental frequency of the simultaneously recorded sound as assessed by speech analysis. Ultrasound imaging is a promising diagnostic and therapeutic tool for the control and development of esophageal speech.

[Ultrasound study of disorders of coordination in tongue movement in swallowing].

Ultrasound imaging of tongue movements permits real-time observation of swallowing and articulation without risk for the patient. The ultrasound images of the tongue motions were recorded on video-tape and then analyzed frame by frame. We were able to detect regular phases of tongue motion during normal swallowing. Clear deviations from normal motion patterns were found in a patient with anarthria, despite absence of swallowing difficulties in every day life.
