Magnetic Resonance Imaging (MRI) systems have good intrinsic SNR (signal-to-noise ratio) and are used an important instrument for diagnosis. Recently, transceive phased array coils using transmission lines in MRI systems have been studied for parallel imaging[1-3], RF shimming[4] and RF homogenization[5]. These coils are composed of several RF resonators that are independently controlled by adjusting the amplitude and phase of the excitation. Microstrip, one of most widely used transmission lines, is used to design a transceive array coil element. The RF resonators using microstrip operate at a Larmor frequency of 128 MHz (3T). In this paper, we introduce four different RF resonators and a slot loaded RF resonator shows better RF efficiencies than other three RF resonators.
