A RF phase gradient transmit coil array, (capable of producing a gradient of either sign) has been designed for the TRASE RF imaging method. The array consists of a Double Maxwell coil and a curved Helmholtz coil to create respectively a sine field and a cosine field. 3D simulations showed large usable volumes for both coil components. Experiments were performed on a vertical field 0.2T MRI system. Field mapping confirmed good homogeneity and phase linearity and a correct RF power drive ratio between the two coil components. 1D TRASE data of four small doped water bottles were acquired successfully.
