Stretchable self-tuning MRI receive coils based on liquid metal technology (LiquiTune)

Abstract Magnetic resonance imaging systems rely on signal detection via radiofrequency coil arrays which, ideally, need to provide both bendability and form-fitting stretchability to conform to the imaging volume. However, most commercial coils are rigid and of fixed size with a substantial mean of...
