要約
(EN)
The image processing device according to an embodiment of the present invention is provided with a detection unit (133b), a generation unit (133c), and a display control unit (133d). The detection unit applies a labeling pulse to a labeling region in an imaging region, and detects a region of a body fluid flowing through a subject from each image included in an imaged time-series group of images. The generation unit generates a display image in which the detected region of body fluid is represented on each image by a display mode based on a positional relationship with a boundary line set in the imaging region. The display control unit displays, in a display unit, a time-series group of display images including a plurality of the display image.

Un mode de réalisation de la présente invention concerne un dispositif de traitement d'image qui est doté d'une unité de détection (133b), d'une unité de génération (133c), et d'une unité de commande d'affichage (133d). L'unité de détection applique une impulsion de marquage à une région de marquage sur une région d'imagerie, et détecte une région d'un fluide corporel s'écoulant dans un sujet à partir de chaque image incluse dans un groupe d'images imagées en série chronologique. L'unité de génération génère une image d'affichage sur laquelle la région détectée de fluide corporel est représentée sur chaque image par un mode d'affichage basé sur une relation positionnelle avec une ligne de délimitation définie sur la région d'imagerie. L'unité de commande d'affichage affiche, sur une unité d'affichage, un groupe d'images d'affichage en série chronologique comprenant une pluralité d'images d'affichage.
