FIELD: physics.
SUBSTANCE: group of inventions relates to a magnetic resonance radio frequency transmitter for purposes of magnetic resonance imaging. Magnetic resonance radio-frequency transmitter for generation and application of radio-frequency excitation field B1 for purposes of magnetic resonance examination comprises a birdcage-type coil and a plurality of radio frequency amplification units for providing radio frequency power at a magnetic resonance frequency for a birdcage-type by a plurality of M activation ports selected from a plurality of N activation ports. In operating condition, the birdcage-type coils, each radio-frequency amplifying unit is electrically connected to the activation port and is located in close proximity to it. There is a set fixed ratio of adjustable phases of magnetic-resonance radio-frequency power among a plurality of radio-frequency amplifying units, which is provided by means of a plurality of M radio-frequency amplifying units.
EFFECT: technical result is simplification of design of magnetic resonance device.
