birdcage body coil at 3T has some considerable disadvantages. Most of all it
has very large power requirements. The use of local transmit arrays severely
reduces these power requirements. In this study, we intend to explore the use
of dipole antennas as transceive surface array elements at 3T. Three designs
are investigated after which a strongly meandering dipole antenna is selected.
An array of eight of these element is used for prostate imaging at 3T in a 8ch.
multi-transmit MRI system. Using 8x200W input power, 12 µT is achieved inside the prostate. Relatively
homogeneous T2w images have been acquired
