In comparison, existing non-invasive methods have limited sampling capabilities and provide limited data. “By providing patients and doctors with more thorough details, continuous and real-time cardiac image monitoring is poised to fundamentally optimize and reshape the paradigm of cardiac diagnoses.” “The increasing risk of heart diseases calls for more advanced and inclusive monitoring procedures,” Xu said. The project builds on the team's previous advances in wearable imaging technologies for deep tissues. The wearable heart monitoring system uses ultrasound to continuously capture images of the four chambers of the heart in different angles, and analyze a clinically relevant subset of the images in real time using a custom-built AI technology. A new wearable, non-invasive heart monitor for humans provides real-time, automated insights on the difficult-to-capture pumping activity of the heart – even when a person is exercising. Ĭardiac imaging is an essential clinical tool to assess long-term heart health, detect problems as they arise and care for critically ill patients. And issues with heart function often manifest only when the body is in motion. This is important because the heart not pumping enough blood is at the root of most cardiovascular disease s. Thanks to custom AI algorithms, the device is capable of measuring how much blood the heart is pumping. “The technology enables anybody to use ultrasound imaging on the go,” Xu said. ![]() Currently, echocardiograms– ultrasound examinations for the heart– require highly trained technicians and bulky devices. The goal is to make ultrasound more accessible to a larger population, said Sheng Xu, a professor of nanoengineering at the University of California San Diego, who is leading the project. The portable device, which is roughly the size of a postage stamp, can be worn for up to 24 hours and works even during strenuous exercise. Engineers and physicians have developed a wearable ultrasound device that can assess both the structure and function of the human heart. ![]()
