Wearable ultrasound

Reading: See how your body works in real time — wearable ultrasound is on its way, Nature, comment 26 June 2024 (via Dr Penguin).

Pretty amazing stuff. A small patch which records ultrasound data.

The battery life currently allows for minute-long videos to be taken intermittently: multiple times per hour over several days.

Gives images like this:

Uploaded image — Fig. 4F from Bioadhesive ultrasound for long-term continuous imaging of diverse organs, Science, 28 June 2022. “The BAUS [BioAdhesive UltrasSound] imaging shows the dynamics of the stomach. The gastric antral cross-sectional area gradually decreases after the subject drinks 450 ml of juice.”

I’d have though trying to get a good image in someone moving around in daily life would be a tough challenge—although well worth going for. It’s just the kind of problem machine learning and the camera industry is good at solving.
