Development of X-ray TV M-mode and reconstructed ultrasound M-mode methods for investigating tongue movement during swallowing in humans

There were two purposes of this study. The first purpose was to introduce the “X-ray TV M-mode waveform” which is reconstructed from sequential X-ray TV images and the “reconstructed ultrasound M-mode waveform” which is delivered from ultrasound B-mode images. The second purpose was to evaluate the...

Description
Summary:There were two purposes of this study. The first purpose was to introduce the “X-ray TV M-mode waveform” which is reconstructed from sequential X-ray TV images and the “reconstructed ultrasound M-mode waveform” which is delivered from ultrasound B-mode images. The second purpose was to evaluate the usefulness of these two types of waveforms in the investigation of tongue movement during swallowing. The instrument system employed in this study consisted of ultrasound and X-ray TV synchronized by a time marker. After the X-ray images and ultrasound B-mode images were recorded on an optical disk, X-ray TV M-mode waveform and ultrasound M-mode waveform were reconstructed using an MC 68030/OS-9 computer. No significant differences in quality of images were observed between the X-ray TV M-mode waveform and the reconstructed ultrasound M-mode waveform. Therefore, both waveforms of the X-ray TV M-mode and the reconstructed ultrasound M-mode are equally useful in measuring tongue movement. (J. Oral Sci. 41, 1-4, 1999)
