Abstract

Magnetic resonance imaging uses RF antenna systems to excite atomic nuclei and to receive the signals emitted by these same nuclei. For ultrahigh field strengths, typically transmit arrays are used to address the RF field inhomogeneity. This study presents an extensive simulation study to explore the best possible transmit coil array design for head imaging (brain) and body imaging (prostate). Results show that for head imaging, loop coils outperform dipoles. The best investigated design consists of eight 22 x 14 cm2 loop coils. For body imaging, the mixed array with 8 dipoles and 24 loop coils performs best.
