5G opens up possibilities for long-distance transmission of ultrasound | Jobs Reply


For people living in remote areas without easy access to doctors or hospitals, 5G connectivity can make telemedicine more effective and efficient than its mobile internet predecessor LTE (similar to 4G), according to a new study published in digital health [1].

In the study – a collaboration between Nagoya University Hospital, the Japanese research institute RIKEN and the Japanese telecommunications company NTT – three subjects living in the remote Japanese municipality of Shinshiro had an abdominal ultrasound scan. The medical staff performed the examination using a mobile ultrasound imaging system and wore a head camera, which transmitted the images in real time to a city hospital.

We found that 5G can transmit information such as 4K images and ultrasound images with high image quality and low latency,” says lead author Masaomi Saeki, assistant professor at Nagoya University’s Graduate School of Medicine, in a press release. “The difference between 4K images and ultrasound images transmitted by 5G and LTE (the 4G network) influenced the subjective evaluation of doctors and physiotherapists.”

Specifically, the two doctors who watched the transmission in the hospital reported that various organs could be evaluated for the video transmitted via 5G without any problems and there were no problems in diagnosing the cases. Although the video transmitted over 5G showed a delay, the doctors rated this delay as “acceptable” and “rather acceptable”.

More problematic, however, was the video transmitted via 4G, with the doctors agreeing that network-related transmission delays were “unacceptable”.
