阵列线圈在MRI中无处不在，并且在MR光谱学中得到越来越广泛的使用。传统的PIN二极管去耦电路需要大量电流来正向偏置二极管。这里提出的方法不需要显著的电流，因此减少了对失谐电流污染B 0均匀性的担忧。此外，所提出的方法将有利于阵列线圈的建设，由于其simplicity.Clinical Relevance-去耦是关键的RF线圈阵列的建设，使快速MR成像。
Array coils are ubiquitous in MRI and are becoming more widely used in MR spectroscopy. Conventional PIN diode decoupling circuits require significant currents to forward bias the diodes. The approach proposed here does not require significant current and thus reduces concerns for contaminating the B0homogeneity with the detune current. Additionally, the proposed approach will facilitate the construction of array coils for MRI due to its simplicity.Clinical Relevance— Decoupling is critical for constructing RF coil arrays and enables rapid MR imaging.
