Electro-textiles as potential candidate of flexible MRI RF coil for stroke prevention

摘要

RF coils are essential part of Magnetic Resonance Imaging (MRI), which is a widely used imaging modality nowadays. Flexible surface RF coils are desired for potential higher signal to noise ratio (SNR) and ergonomic advantages. Electro-textiles are explored as potential candidate for MRI RF surface coils. A Flexible MRI RF coil for transmission or reception using electro-textiles is designed, fabricated and measured for 1.5Tesla MRI. The design of the prototype is targeted towards the carotid artery imaging to prevent strokes, which is one of the leading cause of death world wide. The S11 is −19.8dB at resonant frequency of 122MHz. H1+ field with different conformal radius is shown to demonstrate its potential advantage to increase MRI image quality.
