1. A magnetic resonance imaging system which simultaneously images at least first and second displaced organs of a subject, the system comprising:

  • a main magnet means for generating a static magnetic field through an examination region in which a portion of the subject including the first and second organs is disposed;

    a gradient field means for selectively generating magnetic field gradients across the examination region as a whole;

    a magnetic resonance excitation means for exciting magnetic resonance in at least first and second organs of the subject portion in the examination region;

    a magnetic resonance imaging sequence control means connected with the resonance excitation means and the gradient field means for causing the resonance excitation means and the gradient means to apply RF and gradient field pulses of magnetic resonance imaging sequences to the examination region;

    a first radio frequency coil disposed adjacent the first organ for receiving magnetic resonance signals from the first organ;

    a second radio frequency coil displaced from the first radio frequency coil and disposed adjacent the second organ for receiving magnetic resonance signals from the second organ;

    a first radio frequency receiver means connected with the first radio frequency coil for receiving and demodulating magnetic resonance signals received by the first radio frequency coil;

    a second radio frequency receiver means for receiving and demodulating magnetic resonance signals received by the second radio frequency coil;

    a reconstruction means for reconstructing magnetic resonance signals received and demodulated by the first radio frequency receiver means into first electronic image representations of the first organ and for reconstructing magnetic resonance signals received and demodulated by the second radio frequency receiver means into second electronic image representations of the second organ;

    a video processing means for selectively converting the first and second electronic image representations into a human-readable display.
