an experimental protocol for assessing the performance of new ultrasound probes based on cmut technology in application to brain imaging

イメージング性能の再現性の初期評価を行う可能性はデザインの基礎、開発プロセス (米国) 新しい超音波のプローブします。特に、アプリケーション固有イメージ ターゲットとより現実的な解析は、アプリケーションの潜在的な臨床分野において米国プローブの予想性能を評価するために非常に貴重なことができます。
この作品で提示された実験的プロトコルはアプリケーション固有の評価手順の開発私たちを提供するために設計意図的に関連する容量型マイクロ超音波探触子 (による CMUT) 技術に基づくプロトタイプをプローブ脳イメージング。
プロトコルは、リアリズムと記載されている手順・脳神経から借りたニューロナビゲーション技術は再現性を保証するイメージングのターゲットとして、ホルマリン固定ウシ脳の使用を組み合わせたものです。米国の調査は追跡システムの位置データを取得でき、脳の磁気共鳴 (MR) 画像を参照する米国画像の重ね合わせが動きに実際に接続されます。これは人間の専門家がパフォーマンスをイメージング米国プローブの視覚的質的評価を実行する異なるプローブを使った買収を比較するための手段を提供します。さらに、このプロトコルは、米国画像集録、すなわち完成して開く研究開発システムの利用に関する超音波高度なオープン プラットフォーム (ULA OP) スキャナー。
原稿は、器具の調整、画像の取得および米国および MR 画像の登録プロトコルでは、特に関連する手続の詳細について説明します。得られた結果は、完全再現 (関与の計測範囲) 内で開く、米国画像の獲得そして処理の活動の全体のセットをカバーする示される、全体的なプロトコルの有効性を証明します。

2 D の効果的かつ再現性の評価手法の実験的検証であり、私たちの 3 D イメージング機能プローブによる CMUT 技術、脳に将来のアプリケーションに基づいてプロトタイプ説明プロトコル経由での主な成果イメージング。記述されていたプロトコルのすべての手順を実装した後専門家を適用できます可視化ソフトウェア機能 (無料オリエンテーションのスライスなど</em...
