  • Magnetic resonance imaging foot coil assembly
    Patent number: 5361764
    Abstract: A magnetic resonance imaging receiver system for producing high resolution images of the foot and ankle regions of a human subject. The magnetic resonance imaging receiver comprises an antenna for receiving resonance signals produced by a magnetic resonance imaging, radio frequency excitation magnetic apparatus, a free standing foot cradle assembly for supporting and rigidly holding the foot and ankle of the subject, and a tuning/impedance matching circuit for providing for the maximum transfer of radio frequency energy from the antenna to the receiver unit in the magnetic resonance imaging, radio frequency excitation magnet apparatus. The system utilizes fixed local coils which operate in the receive only mode for receiving electromagnetic signals from resonating nuclei produced by a whole body MRI scanner system or the like to produce high quality images.
