Abstract
As the static magnetic field used in Magnetic Resonance Imaging ('MRI') instruments increases the resonance frequency also increases. Consequently, the signal lost due to the coil becomes an issue. To compensate for this loss, it is possible to use an active device, such as a diode, a transistor, etc., with the radio frequency coil, MRI arrangement and method according to exemplary embodiments of the present invention to generate negative resistance to cancel the coil loss resistance. In this manner, the efficiency of the RF coil at high frequency can be improved.
