An endoscope shows an interior surface image of organ, but it has difficulty finding the information under tissue surface. To assist endoscopy and endoscopic surgery by providing cross-sectional images, we have developed an integrated MR-endoscope system. An intraluminal RF coil to be inserted into esophagus was designed, and MR imaging using this coil and a tracking system to detect the coil position in MRI was conducted using an excised porcine tissue. The layer structure in esophagus could be distinguished in T1- and T2-weighted images. The feasibility of esophagus imaging by the developed coil having high Q value was demonstrated.
