Abstract
(EN)
One aspect of the present disclosure can provide a brain lesion information provision device. The brain lesion information provision device may comprise: a magnetic resonance angiography (MRA) provision unit which provides an environment allowing the display of 3D time-of-flight (TOF) MRA by reflecting a user input; a brain lesion input unit which sets a brain lesion area, combines the set brain lesion area with the 3D TOF MRA, and thereby generates and manages a brain lesion image; a maximum intensity projection (MIP) conversion unit which constructs MIP image data including at least one image frame corresponding to the projection position of the brain lesion image; a noise removal unit which removes noise from brain lesion information in said at least one image frame included in the MIP image data and constructs corrected MIP image data reflecting the brain lesion information having the noise removed therefrom; and an MRA reconstruction unit which reconstructs a corrected brain lesion image by back-projecting the corrected MIP image data.

La présente invention concerne, selon un aspect, un dispositif de fourniture d'informations sur une lésion cérébrale. Le dispositif de fourniture d'informations sur une lésion cérébrale peut comprendre : une unité de fourniture d'une angiographie par résonance magnétique (MRA) qui fournit un environnement permettant l'affichage d'une MRA en temps de vol 3D (TOF) en reflétant une entrée utilisateur·trice; une unité d'entrée de lésion cérébrale qui définit une zone de lésion cérébrale, combine la zone de lésion cérébrale définie à la TOF MRA 3D, et génère ainsi et gère une image de lésion cérébrale; une unité de conversion de projection d'intensité maximale (MIP) qui construit des données d'image MIP comprenant au moins une trame d'image correspondant à la position de projection de l'image de lésion cérébrale; une unité d'élimination de bruit qui retire le bruit provenant des informations de lésion cérébrale dans ladite au moins une trame d'image comprise dans les données d'image MIP et qui construit les données d'image MIP corrigées reflétant les informations de lésion cérébrale desquelles le bruit a été retiré; et une unité de reconstruction MRA qui reconstruit une image de lésion cérébrale corrigée par rétroprojection des données d'image MIP corrigées.
