Abstract

Official abstract text for this publication.

Disclosed herein is a position detection marker that includes a magnetic field source that generates magnetism, an MRI marker that can be detected by a magnetic resonance imaging method, and a holding part that fixes a relative positional relation between the magnetic field source and the MRI marker.

First claim

Opening claim text (preview).

What is claimed is: 1 . A position detection marker comprising: a magnetic field source that generates magnetism; an MRI marker that can be detected by a magnetic resonance imaging method; and a holding part that fixes a relative positional relation between the magnetic field source and the MRI marker. 2 . The position detection marker as claimed in claim 1 , wherein the magnetic field source is a coil. 3 . The position detection marker as claimed in claim 2 , further comprising a connector to/from which a cable can be attached/detached. 4 . The position detection marker as claimed in claim 2 , wherein the MRI marker is disposed in an inner diameter area of the coil. 5 . The position detection marker as claimed in claim 1 , wherein the holding part has a configuration allowing attachment/detachment of the magnetic field source and MRI marker. 6 . The position detection marker as claimed in claim 5 , wherein the holding part includes a housing part housing therein the magnetic field source and MRI marker and a lid part closing the housing part, and wherein the housing part and lid part are fixed to each other by screw engagement or claw engagement. 7 . The position detection marker as claimed in claim 5 , wherein the holding part includes a housing part housing therein the magnetic field source and MRI marker and a lid part closing the housing part, and wherein the lid has an opening exposing the MRI marker. 8 . The position detection marker as claimed in claim 7 , wherein the MRI marker protrudes from the opening of the lid.
