Performance of the RF coil, the antenna of the magnetic resonance imaging (MRI) system, is determined by the intensity of the applied B1 field on the target area. In the case of the human head, the size and shape of the head varies. Hence, in this study, a position-adjustable multi-channel RF coil for 3 Tesla is presented. The proposed RF coil has teeth structure that each coil element of the coil can be adjusted to be closer and be similar with the head shape. We check the B1 field and MR image with a human phantom designed to represent the electrical propoerties of the head to analyze the performance of the proposed RF coil. The result shows that the proposed RF coil will enhance the applied B1 field for better performance.
