发明名称 Endoscopic image pickup method and magnetic resonance imaging device using the same
摘要 An endoscope-like image taking method of the present invention includes a preparation step of providing at least one peculiar index, which can be discriminated from other portions on an MR image, at the tip of a catheter, a first step (S1) of previously inserting a metal guide wire for guiding the catheter into a body cavity of a patient into which the catheter is inserted, a second step (S2) of inserting the catheter into the body cavity along the guide wire, a third step (S3) of executing an MR imaging sequence of a plurality of sliced images intersecting the guide wire, a fourth step (S4) of reconstructing three-dimensional image data based upon the nuclear magnetic resonance signals, which are generated from the patient when the sequence is executed and 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 a fifth step (S5) of 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, thereby an endoscope-like image, which is observed from the catheter in the body cavity of the patient, is taken and displayed in real time or semi-real time so that the insertion of the catheter is supported.
