| Research Abstract |
Zr-based alloys and composites were developed to suppress the MRI artifacts in this study. Magnetic susceptibility of Zr alloys containing Nb or Mo varied depending on the phase constitution and the volume fraction. Also, the magnetic susceptibility was controlled by the integration of Ag which was negative magnetic susceptibility. We showed that artifact volume decreased with decreasing magnetic susceptibility quantitatively. Therefore the developed Zr-based alloy and composites can decrease MRI artifacts.
