摘要：PROBLEM TO BE SOLVED: To provide a device which is useful near the intense magnetic field of a magnetic resonance image scanner, especially an endoscope. SOLUTION: The endoscope includes a main body including at least some metal including parts consisting of a material including metallic components with very low magnetic susceptibility and made from brass consisting of about 62 to 65 wt.% copper and zinc being the other part. This brass material desirably includes about smaller than 0.02 wt.% cadmium, about smaller than 0.03 wt.% iron, about smaller than 0.03 wt.% lead and about smaller than 0.03 wt.% tin and an endoscope like this includes a sinoatrial mirror, a joint mirror, a stomach mirror, a larynx mirror and an uterus mirror.
