Streaming technology: from games to tele-ultrasound

Abstract

BACKGROUND: Due to the gaming industrys rapid development, a large number of technical tools and technologies with unique characteristics have emerged. One of these technologies, which can be potentially used in medical diagnostics, is streaming (online streaming). By connecting an ultrasound scanner to a video capture system, it is possible to significantly expand the diagnostic devices functionality. AIM: To investigate the possibility of applying the gaming industrys information technology in telemedicine, like tele-ultrasound. MATERIALS AND METHODS: In this study, an ultrasound video image was captured using a video capture system developed for gamers. The video was obtained during brachycephalic arteries ultrasound in the following modes: greyscale B-mode, color duplex, and pulse Doppler mode. The examination was broadcast to a video streaming service in real time. RESULTS: An expert sonologist obtained optimal video image parameters and determined the minimum required video streaming settings for an adequate remote evaluation. The following video capture workstation settings are recommended: video, 1280720; 24 fps; H.264 encoder; bitrate, at least 350 Kbps. CONCLUSIONS: Using technical and software tools developed for video game streaming to provide tele-ultrasound is possible.
