Application of Inductively Coupled Wireless Radio Frequency Probe to Knee Joint in Magnetic Resonance Image
Abstract
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.
