<P>PROBLEM TO BE SOLVED: To provide a medical guide, used jointly with tomographic technology such as a magnetic resonance imaging method and a computer tomographic imaging method for guiding a medical instrument to a target region in a subject. <P>SOLUTION: This medical guide includes a base 2 configured to be placed in a subject; and a trajectory guide 5 movably connected to the base, wherein the trajectory guide includes at least one distal marker 7 and at least one proximal marker 8, which is visible by tomographic imaging technology, and the markers are separated from each other by at least one invisible part selected in the tomographic imaging technology. Further, the positioning marker is disposed to optimize a trajectory route and facilitate treatment such as extraction of sample for biopsy using the selected tomographic imaging technology. <P>COPYRIGHT: (C)2009,JPO&INPIT |
