Abstract[English]
A imaging method, comprising: capturing first multiple 2D images of an object (1030, 1032) counting only incident photons with wavelengths shorter than or equal to a first wavelength (1210); reconstructing a first 3D image of the object (1030, 1032) from the first multiple 2D images (1220); capturing second multiple 2D images of the object (1030, 1032) counting only incident photons with wavelengths shorter than or equal to a second wavelength, wherein the second wavelength is shorter than the first wavelength (1230); reconstructing a second 3D image of the object (1030, 1032) from the second multiple 2D images (1240); and generating a third 3D image of the object (1030, 1032) from the first 3D image and the second 3D image (1250).[French]
L'invention concerne un procédé d'imagerie, comprenant les étapes suivantes : capture de premières images 2D multiples d'un objet (1030, 1032) en comptant uniquement les photons incidents ayant des longueurs d'onde inférieures ou égales à une première longueur d'onde (1210) ; reconstruction d'une première image 3D de l'objet (1030, 1032) à partir des premières images 2D multiples (1220) ; capture de deuxièmes images 2D multiples de l'objet (1030, 1032) en comptant uniquement les photons incidents ayant des longueurs d'onde inférieures ou égales à une deuxième longueur d'onde, la deuxième longueur d'onde étant plus courte que la première longueur d'onde (1230) ; reconstruction d'une deuxième image 3D de l'objet (1030, 1032) à partir des deuxièmes images 2D multiples (1240) ; et génération d'une troisième image 3D de l'objet (1030, 1032) à partir de la première image 3D et de la deuxième image 3D (1250).
