Description

第1の導体300は、第1および第2のセグメント304、306の長さに基づいて成長する分布キャパシタンスを示す。第2の導体302は、第1および第2のセグメント308、310の長さに基づいて成長する分布キャパシタンスを示す。第1のセグメント304、308は、第2のセグメント306、310とは異なる長さを有してもよい。第1のセグメント304、308と第2のセグメント306、310との間の長さの相対的な差は、所望の中心周波数で共振周波数を有する有効LC回路を生成するために使用することができる。例えば、第2のセグメント306、310の長さに対して第1のセグメント304、308の長さを変えることによって、一体化された分布キャパシタンスを変えることができる。
図7は、可撓性材料のシートなどの布地支持体740に取り付けられた30個のRFコイル701を含む例示的なRFコイルアレイ700を示す。アレイの各RFコイルは、図2〜図5に関して上述したRFコイルループの非限定的な例であり、一体型キャパシタコイルループ701と、コイルループに直接結合された結合電子回路部703と、を含む。いくつかの例では、アレイのコイルインターフェースケーブルおよび/またはケーブルアセンブリは、円筒形の塊状のバランを排除するためにそれらの長さ全体にわたって連続/隣接するバランを含むことができる。したがって、支持体740に縫合または他の方法で取り付けられたときでも、各RFコイルは多次元における可撓性を維持する。
したがって、本明細書に記載のRFコイルは、2つの平行な導体ワイヤのうちの少なくとも1つに切れ目がないかまたは少なくとも1つの切れ目を有するpTFE誘電体に封入されたツインリード導体ワイヤループと、各コイルループに結合された小型結合電子回路PCBと、を含む。(例えば、約2cm 2 以下の非常に小さい結合電子回路PCB)。PCBは、コンフォーマルコーティングまたは封入樹脂で保護することができる。そうすることで、従来の部品が排除され、キャパシタンスが一体型キャパシタ(INCA)コイルループに「組み込まれる」。コイル要素間の相互作用が減少または排除される。コイルループは、使用される導体ワイヤのゲージ、導体ワイヤ間の間隔、ループ直径、ループ形状、ならびに導体ワイヤの切れ目の数および配置を変えることによって、広範囲のMR動作周波数に適応可能である。
