Cadaver Measurement Results Using Ultra-flexible Electro-textile MRI RF Coil

Current surface Radio Frequency (RF) coils used for neck Magnetic Resonance Imaging (MRI) have two major issues: uncomfortable patients experience and low Signal-to-Noise Ratio (SNR). An ultra-flexible 4-channel receive-only RF coil array for neck imaging was designed and tested in this work using electro-textile material. The flexibility of the material is similar to normal clothes thus leading to considerable ergonomic benefit. The SNR at 3 cm is 5.5 times higher than a standard surface array coil. Cadaver images acquired using the new ultra-flexible coil had good depiction of anatomical features of arteries and muscles with high SNR and the resolution of 1mm × 1mm.
