Abstract:
(EN) A computer-implemented method of imaging an object, and an optical coherent tomography (OCT) imaging system implementing same. The method comprises acquiring a three-dimensional optical coherence tomography (OCT) data set representing an object, wherein the OCT data set includes at least a first and a second three-dimensional data subsets, each element of the OCT data set having a respective sampling period, wherein at least a first element of the first data subset represents a point in space that is not represented by any element of the second subset, and at least one element of the second subset has a sampling period different from the sampling period of the first element of the first subset; processing at least the first and the second data subsets according to at least one imaging modality, thereby generating at least a first and a second processed data subsets, each processed data subset representing the object; and generating a composite image representing the object based on at least the first and the second processed data subsets.
(FR) Procédé mis en œuvre par ordinateur consistant à imager un objet, et système d'imagerie par tomographie par cohérence optique (OCT) mettant en œuvre celui-ci. Le procédé consiste à acquérir un ensemble de données de tomographie par cohérence optique (OCT) en trois dimensions représentant un objet, l'ensemble de données OCT comprenant au moins un premier et un second sous-ensemble de données en trois dimensions, chaque élément de l'ensemble de données OCT ayant une période d'échantillonnage respective, au moins un premier élément du premier sous-ensemble de données représentant un point dans l'espace qui n'est représenté par aucun élément du second sous-ensemble, et au moins un élément du second sous-ensemble ayant une période d'échantillonnage différente de la période d'échantillonnage du premier élément du premier sous-ensemble; à traiter au moins le premier et le second sous-ensemble de données selon au moins une modalité d'imagerie, ce qui permet de produire au moins un premier et un second sous-ensemble de données traitées, chaque sous-ensemble de données traitées représentant l'objet; et à produire une image composite représentant l'objet sur la base au moins du premier et du second sous-ensemble de données traitées.
