This work evaluates the feasibility of wireless real-time ultrasound image streaming, for use in disaster, rescue and medical transport. Relevant transmission parameters (data rate, packet loss, jitter, and latency) and network protocols were measured for 3 wireless networks: 802.11g ad-hoc network, 3G cellular broadband network, and Inmarsat BGAN satellite network. In addition, H.264 compressed echocardiographic image loops were transmitted in real-time over the 3 wireless networks, with specified image quality (VGA and QVGA) and specified frame rates (10, 15, 20 and 30 frames per second), and then uncompressed and recorded. Physicians with expertise in medical ultrasound subsequently rated the diagnostic content of the transmitted image stream relative to the original image loops. The results showed that with efficient video compression, diagnostically valuable wireless streaming of ultrasound video can be carried out. This work will benefit individuals and organizations in the...Похожие книги
