Abstract
Description
コントラスト=PROI-Pbkg
ここで、PROIは、対象領域の平均ピクセル強度であり、Pbkgは周囲背景の平均ピクセル強度である。
コントラスト測定は、ディップコーターを使用して微粒子を含むコーティングの薄膜が付加されたポリウレタンチューブで実行された。PUチューブ上の微粒子の面密度は、顕微鏡下で1mm2あたりの微粒子の数を数えることによって決定された。コントラスト測定は、10MHzで動作するリニアアレイ超音波プローブを使用して、テスト媒体として超音波ファントム中で実施された。チューブは、超音波プローブに対して約45°の角度で挿入された。ポリウレタンチューブの遠位端は、試験媒体の内側8cmの深さに配置された。
