In this work, a high resolution whole mice body image using mechanically sliding coil array was demonstrated for interventional MR. Three fixed coil arrays were situated on the bottom of mice body while the mechanically mobile small coil loop with high S/N, was put on the top of mice head to perceive higher S/N on the volume of interest (VOI). One high SNR quality image of mice head captured by mobile loop and three homogenous quality images of mice body acquired by associated fixed rectangular coils were acquired and used for image reconstruction using parallel imaging to speed up imaging time. Compared with conventional array coils, this design offers more freedom for target detection and offers higher SNR on the target area.
