Abstract
A body coil assembly for a magnetic resonance apparatus has a first coil and a second coil for generating a radio-frequency field in space, and a power control apparatus connected to the first coil and the second coil for controlling the transmitting power of the first coil and the second coil. In a method for generating a radio-frequency field using such a body coil assembly, the transmitting powers of the first coil and the second coil are controlled, to provide unequal transmitting powers to the first coil and the second coil when needed to generate a required radio-frequency field distribution, so as to form a stronger field strength at a certain position, thus improving the signal to noise ratio at that position during the receiving process.
