<P>PROBLEM TO BE SOLVED: To provide a marker for medical imaging capable of correctly specifying a reference point (a central point) on a captured image. <P>SOLUTION: This marker is provided with a base 2 formed of a non-contrast material, three spherical bodies 10, 11 and 12 disposed inside a base 2 in a predetermined positional relationship and formed of a contrast material, and auxiliary marker bodies 20, 21 and 22 formed of a contrast material inside the base 2. The auxiliary marker bodies 20, 21 and 22 have straight line parts 20L, 21L and 22L of a predetermined length, being parallel to a straight line passing the central points of the three spherical bodies 10, 11 and 12 and possibly served as markers. In the captured image, the central points of the three spherical bodies 10, 11 and 12 are correctly specified by referring to the straight line parts 20L, 21L and 22L of the auxiliary marker bodies 20, 21 and 22 so as to correctly specify the reference shaft of the image. <P>COPYRIGHT: (C)2009,JPO&INPIT |
