This work evaluates the feasibility of wirelessreal-time ultrasound image streaming, for use indisaster, rescue and medical transport. Relevanttransmission parameters (data rate, packet loss,jitter, and latency) and network protocols weremeasured for 3 wireless networks: 802.11g ad-hocnetwork, 3G cellular broadband network, and InmarsatBGAN satellite network. In addition, H.264 compressedechocardiographic image loops were transmitted inreal-time over the 3 wireless networks, withspecified image quality (VGA and QVGA) and specifiedframe rates (10, 15, 20 and 30 frames per second),and then uncompressed and recorded.Physicians with expertise in medical ultrasoundsubsequently rated the diagnostic content of thetransmitted image stream relative to the originalimage loops. The results showed that with efficientvideo compression, diagnostically valuable wirelessstreaming of ultrasound video can be carried out.This work will benefit individuals and organizationsin the field of telemedicine and remote medicalimaging as well as those in the wireless community.
