In this work, we explore a conformal Tic Tac Toe (TTT) head coil design for ultra-high field MRI. By conforming the antennas to the human head, we can extract better homogeneity allowing for better radiofrequency shimming. The comparison between the traditional TTT design and the conformal TTT design shows expanded coverage, reduction of the coefficient of variation by 0.4% and same intensity for the 16-channel version. The conformal designs are extremely flexible as its advantages can be explored for different configurations and sizes.
