This self-powered sensor (circled in yellow) attached to a headrest within an MRI machine could help make imaging collection more efficient by detecting patient movement in real time. Credit: ACS Sensors (2024). DOI: 10.1021/acssensors.4c00319 MRI scans are commonly used to diagnose a variety of conditions, anything from liver disease to brain tumors. But, as anyone who has been through one knows, patients must remain completely still to avoid blurring the images and requiring a new scan. A prototype device described in ACS Sensors could change that. The self-powered sensor detects Read More
