A Novel Voltage Controlled Decoupling Method for Transmit Coils in MRI Conference Paper

abstract

• 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 B0 homogeneity 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.
