In this study the performance of a five turns micro helix coil wound on an SU8 cylinder, was evaluated by mapping its 2D B1 and B0 field’s distribution. These tests are done inside doped water phantom, on a 9.4T using 3D GE sequences. B1 maps are acquired using multi flip angle MFA method and B0 mapping are performed by measuring frequency deviation inside a doped water phantom. In General, Results show that coil has enough SNR and provides minimum frequency deviation and maximum B1 uniformity across the sample and particularly at the coil center.
