High speed vocal fold imaging using smartphone-based laryngoscope: A preliminary study

In recent, performances of smartphones are highly developed and they can acquire high resolution image with high framerates. The objective of this study is the development of smartphone-based laryngoscope to reduce the cost of device and demonstrate possibility of highspeed vocal cord imaging by utilizing high performance smartphone camera. We designed customized smartphone adapter for combining clinical laryngoscope and Samsung smartphone. By attaching conventional clinical probes into our customized smartphone adaptor, the high-speed vocal cord endoscopic images were acquired. We could confirm the high-speed digital images of 940fps were acquired from 5 healthy volunteers as a preliminary study.
