Metal transmitter and receiver coils or antennas are currently used in magnetic resonance imaging (MRI) and positron emission tomography (PET) in conjunction with MRI. This presentation shows various experiments that were done to show advantages of using plasma coils or antennas instead of metal coils or antennas in magnetic resonance imaging (MRI) and positron emission tomography (PET) in conjunction with magnetic resonance imaging. The metal antenna coils were removed from an MRI machine and replaced by plasma antennas in the form of simple fluorescent tubes. The first in vivo imaging was done with plasma antennas in an MRI machine.  Of course plasma antennas as fluorescent tubes are not the optimal plasma antenna design for MRI and MRI/PET applications. The problem with metal transmit and receive antennas in an MRI machine is that they interfere with each other. This problem is greatly reduced or eliminated using plasma antennas. In MRI machines combined with PET, the metal antenna coils greatly attenuate the gamma ray paths which are used to locate tumors. Plasma antenna coils greatly reduce or eliminate this problem.
