ESTIMATING ENDOLUMINAL PATH OF ENDOLUMINAL DEVICE ALONG LUMEN

To provide methods for estimating an endoluminal path of an endoluminal device through a lumen.SOLUTION: A sequence of radiographic images of a portion of a subject's body in which a lumen is disposed is acquired while an endoluminal device 26 including one or more radiopaque portions 27 moves through the lumen. Locations at which the one or more radiopaque portions of the endoluminal device were imaged during the movement of the endoluminal device through the lumen are identified by analyzing the sequence of radiographic images. A set of locations at which the one or more radiopaque portions were disposed during the movement of the endoluminal device through the lumen is defined, and an endoluminal path of the device through the lumen is estimated based upon the set of locations.SELECTED DRAWING: Figure 1 【課題】内腔を通る前記管腔内デバイスの管腔内経路を推定する方法を提供する。【解決手段】１つ又は複数のＸ線不透過部２７を備える管腔内デバイス２６が内腔を通って移動する間に内腔が置かれている対象者の体の一部において、一連のＸ線画像シーケンスが取得される。Ｘ線画像シーケンスを分析することによって、内腔を通って管腔内デバイスが移動する間における管腔内デバイスの１つ又は複数のＸ線不透過部が撮像された位置が識別される。内腔を通って管腔内デバイスが移動する間に１つ又は複数のＸ線不透過部が置かれた位置のセットが画定され、内腔を通るデバイスの管腔内経路がこの位置のセットに基づいて推定される。【選択図】図１
