Synopsis

Keywords: New Devices, BodyA wireless, battery-powered, MR-compatible ultrasound device consisting of an integrated RF/wireless coil, an organ-configuration motion sensor and its associated electronics was used to acquire OCM sensor signals on a healthy volunteer. Signals were obtained that characterized internal motion, which were wirelessly transmitted to the console room. Validation was performed against a real-time MR acquisition.
