Abstract:
An endoscope-like image taking method includes providing at least one peculiar index, which can be discriminated from other portions on an MR image, at the tip of a catheter, previously inserting a metal guide wire for guiding the catheter into a body cavity of a patient inserting the catheter into the body cavity along the guide wire, executing an MR imaging sequence of a plurality of sliced images intersecting the guide wire, reconstructing three-dimensional image data based upon the nuclear magnetic resonance signals, which are received by the guide wire, and determining the tip position and the inserting direction of the catheter by detecting the peculiar index provided at the tip of the catheter based upon the three-dimensional image data, and reconstructing the center projected image using the three-dimensional image data and setting the tip position and the inserting direction of the catheter as a view point and a line-of-sight direction and displaying the center projected image on a display means.
