1 Talk Outline Digital Imaging: Clinical & Research Implications Rita R. Patel, Ph.D., CCC-SLP Assistant Professor Department of Speech & Hearing Sciences Laryngeal imaging Instrumentation Digital Imaging Kymography Current Research Clinical applications Basic science Case Examples Laryngeal imaging Looking at the vocal folds Laryngeal imaging Laryngeal imaging Endoscopy Stroboscopy Assessment of Dysphonia Correlating structure with function Assessment of vocal fold structure Assessment of vocal fold function Histological layers vibrate as 2 structures Body: Vocalis Cover: Epithelium and Lamina Propria Biomechanical structure :2 layers Active [Body] Passive [Cover] Body-Cover Theory Hirano,
2 Laryngeal Imaging Films Stroboscopy Digital Imaging (HSDI) Digital Kymography (Wittenberg et al, 1997) Kymography Video Kymography (Švec et al, 1996) Assessment of function Stroboscopy a current gold standard But Produces apparent motion Stroboscopy: Principle Stroboscopy produces an optical illusion of several segments of different cycles In contrast to continuous light, the stroboscopic light emits rapid pulses These illuminated points are fused together to provide an average vibratory pattern High speed vs. Stroboscopy Montage of glottal cycles Hirano & Bless, 1993 Patel, Dailey & Bless, 2008, Annals of ORL High speed vs. Stroboscopy Schematic representation Stroboscopy Drawbacks Pitch tracking errors Blurred images in disorders, because of pitch tracking problems Aphonic patients strobe light not useful, as no movement will be observed Patel, Dailey & Bless, 2008, Annals of ORL 2
