What can be seen in videokymographic images?

Kymographic imaging refers to a special way of displaying vibrations by putting together a great number of successive images of a vibrating object viewed through a thin slit. In medicine, the method has been found particularly well suited for imaging vibrations of the vocal folds, which are the ultimate source of human voice. Here we address the question on which vibratory characteristics of the vocal folds can be identified in high-speed videokymographic images and used in clinical practice when diagnosing origins of voice problems? The ultimate long-term goal of the research is to relate the displayed vibration characteristics to the tissue properties of the vocal folds and design strategies how undesirable tissue properties can be altered through conservative or surgical treatment.
