Description
MRIで金属アーチファクトを生じない医療用デバイスを作製するには,周囲の組織に近い体積磁化率を示す反磁性の金属材料が必要である.我々は,生体親和性の高い反磁性元素であるAuをベースとし,目標磁化率と高強度を同時に発揮する合金の開発を進めており,Ti-6Al-4V合金やCo-Cr-Mo合金と同等以上の強さを示すAu合金が得られる可能性が見えてきた.
Description Alternative
MRI artifact-free biomedical devices require diamagnetic metals indicating small volume-magnetic-susceptibility mismatch between the metal and surrounding tissues. The authors have developed new alloys based on Au, a biocompatible diamagnetic element, demonstrating susceptibility values close to surrounding tissues and high strength, simultaneously. And they found candidate Au alloys exhibiting strength similar to or higher than Ti-6Al-4V alloy and Co-Cr-Mo alloy.
