Wireless, Web-Based Interactive Control of Optical Coherence Tomography with Mobile Devices.
Abstract
PURPOSE: Optical coherence tomography (OCT) is widely used in ophthalmology clinics
and has potential for more general medical settings and remote diagnostics. In anticipation
of remote applications, we developed wireless interactive control of an OCT system
using mobile devices. METHODS: A web-based user interface (WebUI) was developed to
interact with a handheld OCT system. The WebUI consisted of key OCT displays and controls
ported to a webpage using HTML and JavaScript. Client-server relationships were created
between the WebUI and the OCT system computer. The WebUI was accessed on a cellular
phone mounted to the handheld OCT probe to wirelessly control the OCT system. Twenty
subjects were imaged using the WebUI to assess the system. System latency was measured
using different connection types (wireless 802.11n only, wireless to remote virtual
private network [VPN], and cellular). RESULTS: Using a cellular phone, the WebUI was
successfully used to capture posterior eye OCT images in all subjects. Simultaneous
interactivity by a remote user on a laptop was also demonstrated. On average, use
of the WebUI added only 58, 95, and 170 ms to the system latency using wireless only,
wireless to VPN, and cellular connections, respectively. Qualitatively, operator usage
was not affected. CONCLUSIONS: Using a WebUI, we demonstrated wireless and remote
control of an OCT system with mobile devices. TRANSLATIONAL RELEVANCE: The web and
open source software tools used in this project make it possible for any mobile device
to potentially control an OCT system through a WebUI. This platform can be a basis
for remote, teleophthalmology applications using OCT.
