Abstract:
(EN) In a catheter for acquiring cross-sectional images of a blood vessel, an X-ray image including the catheter inserted into the blood vessel is input. The catheter includes a transmission/reception unit for transmitting/receiving wave signals, and successively acquires, at a predetermined sampling rate, the wave signals received with the transmission/reception unit. From the X-ray image that has been input, the state of arrangement of the catheter and the position of the transmission/reception unit are detected. A three-dimensional image of the blood vessel is created by lining up the successively acquired cross-sectional images at positions corresponding to the path taken by the transmission/reception unit, which is indicated by the detected state of arrangement of the catheter, and perpendicularly to said path.
(FR) L'invention concerne un cathéter dans lequel, pour acquérir des images transversales d'un vaisseau sanguin, une image radiologique, qui comprend le cathéter introduit dans le vaisseau sanguin, est saisie. Le cathéter comprend une unité d'émission/réception pour émettre/recevoir des signaux d'onde et acquiert successivement, à un taux d'échantillonnage prédéterminé, les signaux d'onde reçus avec l'unité d'émission/réception. À partir de l'image radiologique qui a été saisie, l'état d'agencement du cathéter et la position de l'unité d'émission/réception sont détectés. Une image tridimensionnelle du vaisseau sanguin est créée en alignant les images transversales acquises successivement à des emplacements correspondant au trajet pris par l'unité d'émission/réception, qui est indiqué par l'état d'agencement détecté du cathéter, et perpendiculairement audit trajet.
(JA)  血管の断面画像を取得するためのカテーテルにおいて、血管内に挿入されたカテーテルを含むX線画像を入力する。前記カテーテルは波動信号を送受信する送受信部を有し、該送受信部にて受信された波動信号を所定のサンプリングレートで順次取得する。入力したX線画像から、カテーテルの配置状態及び前記送受信部の位置を検出する。順次取得した断面画像を、検出したカテーテルの配置状態が示す前記送受信部の軌跡の対応する位置で、かつ前記軌跡に対して垂直に並べることで、血管の3次元画像を生成する。
