Abstract
The present invention is directed to a system comprising a body coil () for magnetic resonance imaging and an RF amplifier connected to the body coil () for feeding the body coil () with an RF signal, wherein the body coil () comprises two different ports () for feeding the RF signal into the body coil (), the body coil () is provided with a switch for selectively activating only one single port () for feeding the RF signal to the body coil () at a time, and the two ports () are located at different locations of the body coil () such that the dependence of the reflected part of the RF signal fed into the body coil () from the weight of the examination object () to which the body coil () is applied is different for the two ports (). In this way, a possibility for adapting a MRI measurement to different load situations due to different weights of an examination object () in an easy and efficient way is provided, thereby providing the possibility for impedance matching of the body coil by selecting the appropriate driven port.
