An inductively coupled wireless coil for a radio frequency (RF)
probe has been designed and applied to a human knee joint to
improve the signal to noise ratio (SNR) in a magnetic resonance
image (MRI). A birdcage type of a primary coil and a
Helmholtz type of a wireless secondary coil have been
manufactured. The coils were applied to a human knee with a
3 T MRI system. SNR was calculated both in the proton
density image and in the T2 weighted image of MRI. The
experimental results show that the designed coils are effective to
increase SNR in the human knee MRI. Full Text
