Title (EN) PHOTOACOUSTIC APPARATUS AND OBJECT INFORMATION ACQUIRING METHOD
(FR) APPAREIL PHOTOACOUSTIQUE ET PROCÉDÉ D'ACQUISITION D'INFORMATIONS SUR UN OBJET
Abstract:
(EN) A photoacoustic apparatus comprises a light source configured to irradiate an object with light; an acoustic wave detection unit configured to receive an acoustic wave generated in the object by the irradiation of the light, and to convert the acoustic wave into an electric signal; a control unit configured to set an imaging period corresponding to an approximately periodic motion of the object, and to execute the irradiation of the light and acquisition of the electric signal at a timing in an approximately same phase in each imaging period; a composition unit configured to compose a plurality of electric signals acquired in each of the imaging periods; and an image generating unit configured to generate image data representing characteristic information of the object, based on the composed electric signal.
(FR) Selon l’invention, un appareil photoacoustique comprend une source de lumière configurée pour irradier un objet avec de la lumière ; une unité de détection d'onde acoustique configurée pour recevoir une onde acoustique générée dans l'objet par l’irradiation de la lumière et pour convertir l'onde acoustique en un signal électrique ; une unité de commande configurée pour régler une période d'imagerie correspondant à un mouvement approximativement périodique de l'objet, et pour mettre en œuvre l'irradiation de la lumière et l'acquisition du signal électrique à des instants situés dans une phase approximativement identique dans chaque période d'imagerie ; une unité de composition configurée pour composer une pluralité de signaux électriques acquis dans chacune des périodes d'imagerie ; et une unité de génération d'images configurée pour générer des données d'image représentant des informations caractéristiques de l'objet, sur la base du signal électrique composé.
