Synopsis

Keywords: Non-Array RF Coils, Antennas & Waveguides, RF Arrays & Systems, WIFI, wireless, neonatal

Neonatal neuroimaging can be significantly improved using a form-fitting, lightweight coil array that is untethered from the scanner for a high SNR and reduced setup time. An iRFW coil array does this by performing simultaneous RF signal acquisition and wireless data transfer with the same coil element. Proof-of-concept simulations of a form-fitting soccer-ball geometry 16-channel iRFW coil head array show a high and uniform SNR in the neonatal head and WIFI 6 antenna gain patterns that radiate power outside the bore using a 2x1 multiple-input multiple-output WIFI 6 scheme for the high data rate wireless transmission of MRI data.
