Wearable Sensor Provides Cardiac Imaging on the Go

The unique design of the sensor makes it ideal for bodies in motion.

The wearable uses ultrasound to continuously capture images of the four chambers of the heart at different angles, and analyze a clinically relevant subset of the images in real time using custom-built AI technology.

A team led by researchers at the University of California, San Diego (UC San Diego) has developed a portable ultrasound device that uses custom algorithms to measure how much blood is being pumped by the heart.

The postage-stamp-sized patch captures images of the heart at different angles using ultrasound.

The technology performs real-time analysis of a subset of the images, which have high spatial resolution, temporal resolution, and contrast.

UC San Diego's Ruixiang Qi said the device provides "accurate and continuous waveforms of key cardiac indices in different physical states, including static and after exercise, which has never been achieved before."
