Goal of the project was to design a transceive RF coil for imaging small tissue specimen on a human-scale 3T MR scanner. Besides high SNR, high homogeneity and stability of the B1+ field, a major objective was to minimize RF heating. Two perpendicular Helmholtz coil pairs were combined to obtain a quadrature coil. To achieve a high degree of accuracy during coil fabrication, the whole 3D design was made from printed circuit board material. Differential-mode sheath waves were easily and aperiodically suppressed by connecting the coax cable shields with a few resistors.
