Mehta and Robert E. Hillman 1. Early researchers who attempted to produce stroboscopic images of vocal fold behavior had difficulty because: a clear image of the larynx was not possible the patient did not tolerate the procedure well there was a lack of adequately trained personnel to perform the procedure they had to determine the correct relationship between the vocal fundamental frequency and the flash rate of the strobe light being used 2. Fiber optic technology: allowed clinicians to examine individuals that previously could not tolerate imaging procedures allowed clinicians to capture slow motion images of vocal fold behavior was the first major advance in laryngeal imaging was first used in laryngeal imaging in the 1930s 3. Videokymography: allows the user to view the entire larynx at high-speed frame rates requires the clinician to pass a light through a perforated pinwheel samples a very small section of the video image at an exceptionally high frame rate is cumbersome because it requires large reels of cinematic film 4. A significant problem associated with modern laryngeal high-speed videoendoscopy is: that it is difficult to develop adequate data processing techniques the elevated risk to the patient finding appropriate research subjects getting adequate light to the larynx 5. Dynamic optical coherence tomography: is an alternative to endoscopy that provides excellent surface visualization of the mucosa allows imaging of tissue beneath the surface of the vocal fold is a common laryngeal imaging technique used in most voice clinics provides similar information to videokymography Additional Resources FiguresReferencesRelatedDetails Volume 22Issue 1July 2012Pages: C1-C1 History Published in issue: Jul 1, 2012 Get Permissions Add to your Mendeley library Metrics Topicsasha-topicsasha-sigsasha-article-typesleader-topicsCopyright & Permissions© 2012 American Speech-Language-Hearing AssociationPDF downloadLoading ...
