Parallel transmit multi-port volume coils are becoming important due to increased field strengths in order to improve B1+ homogeneity and to minimize Specific Absorption Rate (SAR). Y. Zhu introduced a design for a parallel transmit volume coil, constellation coil that does not require tuning and is scalable to various field strengths. In this work, we have introduced a modified constellation coil that improves the B1+ homogeneity of Zhus design, and makes the B1+ profile similar to the birdcage structure.
