A wireless MR-compatible ultrasound-based device consisting of an integrated RF/wireless coil, organ-configuration motion sensor, Raspberry Pi, pulser/receiver, and analog-to-digital converters was developed to acquire, digitize, and wirelessly transmit ultrasound data while simultaneously acquiring MR-images. Experiments were performed to demonstrate the system's 1) mobility through continuously acquiring, digitizing, and wirelessly transmitting ultrasound data at multiple locations, and 2) ability to wirelessly monitor physiological motion during coughing/gasping. This integrated system enables the OCM sensor to travel with patients throughout the hospital while also demonstrating the ability of the iRFW coil and backend electronics to process and wirelessly transmit a high-fidelity signal.
