APPARATUS INTENDED TO BE USED FOR SPECIMEN WITHIN MAGNETIC FIELD AND METHOD OF BUILDING THE SAME INTENDED TO BE USED WITHIN THE MAGNETIC FIELD

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method of building the apparatus which enables using of the apparatus within a magnetic field without exhibiting a magnetically twisting effect. SOLUTION: An apparatus is so arranged to be made of a carbon fiber material selectively doped by a doping agent. The apparatus has a magnetization rate so adjusted to be equal to the part of a specimen imaged. As a result, there is little effect of a magnetic flux line and a magnetic field on uniformity, hence reducing the distortion of an MR image. The apparatus made of the carbon fiber shows no magnetically twisting force when inserted into the magnetic field. The carbon fiber doped has a minimized effect on a wireless frequency field. The apparatus will not affect a uniform magnetic field applied and the uniformity of any wireless frequency field. The doped carbon fiber exhibits sufficiently high rigidity to enable the building of an apparatus with a higher strength while having a capability of maintaining a sharp edge. A surgical device made of the doped carbon fiber can be used within the magnetic field during the magnetic resonance imaging thereby enabling generating and displaying of an interactive internal image for surgeons during the operation.
