To present a practical scheme of a simultaneous RF transmit and receive (STAR) system for MRI, discuss the challenges and solutions, and show preliminary in vivo MR images obtained with this new technique. A remotely controlled STAR system was built and tested with a transverse electromagnetic (TEM) head coil on a 4T (Oxford, 90 cm-bore) MRI scanner equipped with an Agilent DirectDrive™ console. In vivo head images have been acquired using continuous sweep excitation and acquisition. The bench-test and MR experimental results show our STAR system to have high isolation (60 dB) between transmit and receive with insensitivity to load swings created by head motion. To acquire in vivo head images, ultra-low RF peak power of 50 mW was used. A novel motion-insensitive STAR MRI technique was developed and experimentally tested. The first in vivo MR images using this method were acquired.
