Although videostroboscopy is used most commonly in a clinical setting to image the larynx, it has several drawbacks that can be overcome by using high-speed imaging of the larynx. High-Speed Digital Imaging (HSDI) of the larynx has been performed since the 1930’s but remained impractical for clinical use until recently because of high cost and cumbersome equipment. The development of commercially available high-speed imaging systems using smaller, more affordable cameras has now made it possible to use this technology in a clinical setting. High-speed imaging has the potential to advance the functional assessment of vocal pathophysiology, ultimately improving the ability to diagnose and manage vocal fold (VF) pathology. Recent advances include color imaging and the ability to accurately synchronize and compare VF vibration and acoustic data. However, several barriers to widespread clinical use of this technology remain. This chapter will review recent advances and ongoing challenges in the clinical use of HSDI compared to videostroboscopy.
