Synopsis

Keywords: RF Arrays & Systems, New Devices, Coils, Stretchable

We report on the development of an 8-channel stretchable array coils for 3T knee MRI which was rapidly designed using embroidered conductive threads on athletic fabric. The coil is omnidirectionally stretchable and conforms to the anatomy. Phantom testing shows the coil’s signal-to-noise ratio (SNR), and image quality are comparable to a commercial flexible coil. In vivo imaging was done on a healthy volunteer illustrates the potential of rapidly developed stretchable coils.
