Description
図12の論理流れ図は、図7、9A、9B、10A、10B、11Aおよび11Bに示される撮像装置に対する、本発明の実施形態に従う頭部のCBCT走査の操作シーケンスを示す。受け付け命令ステップS210において、撮像装置は、獲得される画像の種類に関する操作者の命令を受け付け、これは、特定の関心の組織の種類に関する情報を含んでもよい。閾値設定ステップS220において、適切な一連の閾値および他の操作パラメータがセンサ121の回路に読み込まれる。操作者設定ステップS230によって、操作者は、患者の高さおよび患者の頭部の寸法に合わせて架台130コンポーネントを調整することが可能になる。これで、次のヘリカル走査実行のための情報を提供する初期高さ設定を登録する。操作者はまた、患者の位置を調整するために、頭部支持136および整合装置140も使用することができる。命令入力ステップS240は、走査シーケンスを開始し、走査および取得ステップS250を実行する操作者の命令を受け付ける。ステップS250中、複数の2D画像が、CBCT走査データを取得するために、連続した回転および高さの位置で獲得される。次いで、画像生成ステップS260は、ボリューム撮像技術においてよく知られているフィルタリング逆投影ルーチンのうちの1つ等、画像再構成アルゴリズムを使用して、獲得された2D画像から3Dボリューム画像を形成する。得られた画像は、次いで、医療関係者によって視認されるために表示され、画像データは、コンピュータ106にアクセス可能であるメモリ132(図7)または他のメモリ回路に記憶される。
