A 16-channel transceiver loop+dipole antennas head array for human head imaging at 10.5T

Abstract

A loop+dipole transceiver antenna array was designed for 447 MHz /10.5 tesla human head imaging. This was achieved by a geometrically decoupled combination of a loop and a dipole antenna without inter-element decoupling circuitry. We made comparisons between an 8-channel loop only array, an 8-channel dipole only antenna array and a 16-channel loop+dipole combined antenna array through simulation using the finite difference time domain (FDTD) method and MR imaging experiments.
