Abstract This medical system (1) comprises: first light irradiation means (11) for irradiating a coherent light onto an imaging subject; imaging means (12) for capturing a speckle image obtained from the light scattered by the imaging subject irradiated by the coherent light; a speckle contrast calculation means (1312) for calculating, on the basis of the speckle image, a per-pixel speckle contrast value; a movement detection means (1311) for detecting movement of the imaging subject; speckle image generation means (1313) for generating a speckle contrast image on the basis of the speckle contrast value and the movement of the imaging subject detected by the movement detection means; and display means (14) for displaying the speckle contrast image. Ce système médical (1) comprend : un premier moyen d'irradiation de lumière (11) pour irradier une lumière cohérente sur un sujet d'imagerie; un moyen d'imagerie (12) pour capturer une image de granularité obtenue à partir de la lumière diffusée par le sujet d'imagerie irradié par la lumière cohérente; un moyen de calcul de contraste de granularité (1312) pour calculer, sur la base de l'image de granularité, une valeur de contraste de granularité par pixel; un moyen de détection de mouvement (1311) pour détecter un mouvement du sujet d'imagerie; un moyen de génération d'image de granularité (1313) pour générer une image de contraste de granularité sur la base de la valeur de contraste de granularité et du mouvement du sujet d'imagerie détecté par le moyen de détection de mouvement; et un moyen d'affichage (14) pour afficher l'image de contraste de granularité. 医療システム(1)は、コヒーレント光を撮像対象に照射する第1の光照射手段(11)と、前記コヒーレント光が照射された前記撮像対象による散乱光から得られるスペックル画像を撮像する撮像手段(12)と、前記スペックル画像に基いて画素ごとのスペックルコントラスト値を算出するスペックルコントラスト算出手段(1312)と、前記撮像対象の動きを検出する動き検出手段(1311)と、前記スペックルコントラスト値、及び、前記動き検出手段によって検出された前記撮像対象の動きに基いてスペックルコントラスト画像を生成するスペックル画像生成手段(1313)と、前記スペックルコントラスト画像を表示する表示手段(14)と、を備える。
