On the one hand, the SNR increase originates from a higher filling factor and a higher achievable ratio of unloaded to loaded quality factor when the coil is closely form-fitted to the sample. The main benefit expected in comparison to rigid coils is a higher achievable signal-to-noise ratio (SNR) in case of strong variations of the targeted anatomy across patients. Recently, the interest in mechanically flexible RF coil arrays has grown rapidly in the MR community. 832107, “Research Studio for Ultra-High Field MR Applications” to EM, and the Austrian/French FWF/ANR Programme Blanc grant, Austrian Science Fund I1371-B24, “FLEXAR7” to EL.Ĭompeting interests: The authors have declared that no competing interests exist.
