The remote tuning and matching function for intra-cavitary RF coil placed inside the stomach was developed to obtain high quality images of the gastric wall by the integrated MR-endoscope system. The remote tuning and matching circuit consisted of non-magnetic variable capacitors and inductors, and it was placed outside the bore to manually adjust the resonant characteristic of the coil. The SNR of phantom image was improved up to 131 % by using this function. The basic performance of the remote tuning and matching was demonstrated and would be useful for providing high quality images to help diagnosis of GI disease.
