| 摘要 |
<p>An improved intracranial diagnostic electrode (10) for use with magnetic resonance imaging techniques includes an electrode body (16) and at least one metallic contact (11) supported by the body (16). An electrical lead wire (19) is attached to the contact (11) for connecting the contact (11) to a diagnostic instrument. At least the metallic contact (11) is made of an alloy which includes nickel and chronium and is substantially devoid of iron. The electrode (10) thereby provides substantially clear images of the location of each metallic contact (11) when the electrode is used in conjunction with magnetic resonance imaging techniques. The electrode (10) may also include radiopaque elements (25) or markers to adapt the electrode (10) for use with x-ray as well as magnetic resonance imaging techniques. Several embodiments are disclosed.</p> |
