Claim 0:
1. A multi-channel magnetic resonance imaging radio frequency (RF) coil with at least four channels, the RF coil comprising:
a coil element for each of the channels; and
a socket corresponding to each coil element, wherein the socket is electrically coupled to said corresponding coil element via a respective first transmission line, each socket being adapted for receiving a plug for providing an RF signal via the respective first transmission line to the corresponding coil element, wherein with respect to a predefined RF signal differences in electrical length between any of the first transmission lines are kλ/4 resulting in a predefined phase relationship at the sockets, where k is an integer and λ is the wavelength of the RF signal, the RF coil being configured to be driven at the wavelength of the RF signal,
wherein the RF coil has four channels with two pairs of the first transmission lines, wherein within each pair the first transmission lines are of the same electrical length as each other, and wherein the differences in electrical length between the first transmission lines of the two pairs is λ/4.
