Abstract
(EN) An imaging system, according to one embodiment, comprises: an ultrasonic vibration unit for applying an ultrasonic wave to a sample; an image acquisition unit for acquiring a plurality of images of the sample being deformed by the ultrasonic wave; and a computation unit for, from the plurality of images, computing strain caused by a change in thickness of the sample, wherein the computation unit may compute the elastic modulus of the sample through the intensity of the ultrasonic wave and the strain of the sample.
(FR) Un système d'imagerie, selon un mode de réalisation, comprend : une unité de vibration ultrasonore pour appliquer une onde ultrasonore à un échantillon; une unité d'acquisition d'image pour acquérir une pluralité d'images de l'échantillon devant être déformées par l'onde ultrasonore; et une unité de calcul pour, à partir de la pluralité d'images, calculer une contrainte provoquée par un changement d'épaisseur de l'échantillon, l'unité de calcul pouvant calculer le module élastique de l'échantillon au moyen de l'intensité de l'onde ultrasonore et de la contrainte de l'échantillon.
(KO) 일 실시예에 따른 이미징 시스템은, 샘플에 대해 초음파를 가하는 초음파 가진부; 상기 초음파에 의해 변형되는 상기 샘플의 복수 개의 이미지를 획득하는 이미지 획득부; 및 상기 복수 개의 이미지로부터 상기 샘플의 두께 변화에 따른 변형률을 연산하는 연산부;를 포함하고, 상기 연산부는 상기 초음파의 강도 및 상기 샘플의 변형률을 통해 상기 샘플의 탄성계수를 연산할 수 있다.
