Title: Design Decoupling Methods of Multichannel Phased Array Receive Only RF Coil for Different Structures of 1.5T MRI
Abstract: Magnetic Resonance Imaging (MRI) system is based on magnetic field and pulses of radio wave energy to obtain detailed image of internal structures of the body. Use of RF surface coils in MRI is for better signal reception as they are more sensitive to signal as they are close to the body. Hence, for improvement in the performance of the coil, multiple coils are combined together for better signal reception. Multiple small coils are arranged in such a way that it can efficiently cover a specific anatomic region and obtains high resolution, high SNR images of a larger volume. When more than single surface coils are closely situated there will be mutual coupling between the coils, which causes splitting in response at desired resonant frequency. Decoupling is the method to cancel the mutual coupling of the coils such that it will resonate at our desired resonant frequency. Thus decoupling plays a major role in MRI coil.
