Vision Research is a business unit of the Materials Analysis Division of AMETEK Inc., a leading global manufacturer of electronic instruments and electromechanical devices.
While much work and discovery remains, Dr. Deliyski and his team are hopeful for the future of HSV and that it will ultimately supplant stroboscopy as the ‘gold standard’ clinical technique for laryngeal imaging. Not only does HSV possess all the useful features of videostroboscopy, it overcomes the method’s shortcomings and provides new, revolutionary features for more accurate objective and quantification measurements.
This new technology featuring the Phantom
camera has been already implemented at two clinical sites. At the Center for Laryngeal Surgery and Voice Rehabilitation, Massachusetts General Hospital, Boston, M.A., the HSV system became an important component in assessing voice function for patients treated with a revolutionary new laser technique for treating laryngeal cancer developed by Drs. Steven Zeitels and Robert Hillman. At the Voice and Swallowing Center, Charlotte Eye Ear Nose and Throat Associates, Charlotte, N.C., HSV is being tested as part of the day-to-day clinical voice evaluation practice by Dr. Terri Gerlach.
“Our goal is to develop HSV into a robust tool that will provide further insights
into the biomechanics of laryngeal sound production, as well as enable more accurate functional assessment of the pathophysiology of voice disorders. Essentially the heart of our HSV system, the Vision Research
Phantom brings a level of performance and reliability that continues to open new doors
for our research, ultimately leading to
refinements in the diagnosis and
management of vocal fold pathology.”
