Abstract
A magnetic resonance radio frequency transmission device () for generating and applying a radio frequency excitation field Bfor the purpose of magnetic resonance examination comprises a birdcage coil () and a plurality of M radio frequency amplifier units for providing radio frequency power at a magnetic resonance frequency to the birdcage coil () via a plurality of M activation ports () selected out of the plurality of N activation ports (). In an operational state of the birdcage coil () each radio frequency amplifier unit () is electrically connected and is arranged in close proximity to an activation port (). Among the plurality of M radio frequency amplifier units (), there is established a fixed relationship of adjustable phase angles (φ) of the magnetic resonance radio frequency power provided by the plurality of M radio frequency amplifier units (); a method of generating and applying a radio frequency excitation field B for the purpose of magnetic resonance examination, using such magnetic resonance radio frequency transmission device (); and a magnetic resonance imaging system () configured for acquiring magnetic resonance images of at least a portion of a subject of interest (), comprising such magnetic resonance radio frequency transmission device ().
