Abstract
(EN)
A medical system (1) is provided with: an irradiating means (2) which irradiates a subject with coherent light; an image capture means (3) which captures an image of reflected light of the coherent light from the subject; an acquiring means (411) which acquires a speckle image from the image capture means (3); a calculating means (412) which performs a statistical process with respect to each pixel of the speckle image on the basis of the luminance values of the pixel and a peripheral pixel to calculate a predetermined index value; a determining means (413) which, with respect to each pixel, determines whether an average of the luminance values used for calculating the index value is within a predetermined range; a generating means (414) which generates a predetermined image on the basis of the index value; and a display control means (415) which, when the predetermined image is displayed on a display means, causes the displaying to be performed in such a way that a pixel portion for which the average of the luminance values is outside the predetermined range can be identified.
(FR)
La présente invention concerne un système médical (1) pourvu : d’un moyen d’exposition (2) qui expose un sujet à de la lumière cohérente ; un moyen de capture d’image (3) qui capture une image de lumière reflétée de la lumière cohérente provenant du sujet ; un moyen d’acquisition (411) qui acquiert une image de granularité à partir du moyen de capture d’image (3) ; un moyen de calcul (412) qui effectue un processus statistique par rapport à chaque pixel de l’image de granularité sur la base des valeurs de luminance du pixel et d'un pixel périphérique pour calculer une valeur d’indice prédéterminée ; un moyen de détermination (413), lequel, par rapport à chaque pixel, détermine si une moyenne des valeurs de luminance utilisées pour calculer la valeur d’indice se situe à l’intérieur d’une plage prédéterminée ; un moyen de génération (414) qui génère une image prédéterminée sur la base de la valeur d’indice ; et un moyen de commande d’affichage (415), lequel, lorsque l’image prédéterminée est affichée sur un moyen d’affichage, amène l’affichage à être effectué d’une manière telle qu’une partie d’un pixel pour laquelle la moyenne des valeurs de luminance se situe à l’extérieur de la plage prédéterminée peut être identifiée.

医療システム(1)は、被写体にコヒーレント光を照射する照射手段(2)と、前記被写体からの前記コヒーレント光の反射光を撮像する撮像手段(3)と、前記撮像手段(3)からスペックル画像を取得する取得手段(411)と、前記スペックル画像の各画素について、当該画素と周辺画素の輝度値に基いて統計的な処理を行って所定の指標値を算出する算出手段(412)と、前記各画素について、前記指標値の算出に用いた前記輝度値の平均が所定範囲内であるか否かを判定する判定手段(413)と、前記指標値に基いて所定画像を生成する生成手段(414)と、前記所定画像を表示手段に表示する場合に、前記輝度値の平均が前記所定範囲外である画素の部分を識別可能に表示する表示制御手段(415)と、を備える。
