現在用いられている多くの人工肩関節の骨頭部分は球または楕円への近似で設計されている。しかし、同形状は実際の上腕骨頭形状を十分に表現しているとは言い難い。本研究では、人工肩関節設計の目安と成り得る三次元形状を把握するため、上腕骨頭の三次元統計的モデル(SSM)作成法を示す。本手法では、まず肩関節CT画像から上腕骨領域を抽出し、抽出領域から上腕骨形状に基づく座標系を決定する。求めた座標系を基準に位置姿勢を校正し、主成分分析によって上腕骨頭のSSMを取得する。実験では被験者8例から上腕骨頭SSM...

肩腱板修復術の手法は肩腱板断裂の形態によって決定される.断裂形態の診断にはMR画像が用いられる.しかし,MR画像にはスライス間隔が少なからず生じる.したがって,MR画像のみを用いて3次元的な断裂形態を把握することは容易ではない.そこで本研究では,MR画像から半自動的に肩腱板3次元形状を再構築する方法を提案する.はじめに,上腕骨,肩腱板正常部,肩腱板断裂部の3つの領域を手動抽出する.手動抽出した領域はMR画像の輝度情報に基づき,動的輪郭モデルSnakesによって微修正する.その後,陰関数を用...

子宮は筋組織で構成され,子宮筋層の収縮が波のように伝播する子宮ぜん動が生じる.ぜん動は卵巣ホルモンで制御され,胚の着床を助けるなど妊娠,出産で重要な役割を担う.Cine MR画像で観察した子宮ぜん動頻度と妊娠率に相関があることが報告されており,適切なぜん動を促す治療で妊娠率向上が期待できる.しかし,現在のぜん動頻度評価は医師による目視評価で客観性に欠ける.本研究ではCine MR画像による子宮ぜん動の自動定量化法を提案する.提案手法ではまず子宮の動き・変形を補正するために各フレーム間におい...
