DISPOSITIF D'IMAGERIE OPTOACOUSTIQUE ENDOSCOPIQUE, EN PARTICULIER POUR L'IMAGERIE OPTOACOUSTIQUE ENDOSCOPIQUE DE CAVITÉS ET D'OBJETS CREUX

摘要

The invention relates to a device (1) for endoscopic optoacoustic imaging comprising an imaging unit (2) configured to be at least partially inserted into an object (5), said imaging unit (2) comprising an irradiation unit (6) configured to irradiate a region of interest (7) inside the object (5) with electromagnetic radiation and a detection unit (8) comprising at least one ultrasound transducer configured to detect ultrasound waves generated in the region of interest (7) in response to irradiating the region of interest (7) with the electromagnetic radiation and to generate according detection signals, wherein the at least one ultrasound transducer exhibits a field of view (8b) being at least partially located in the irradiated region of interest (7). The device (1) further comprises a position stabilizing structure (3) with an outer face (3a) and an interior (3b) and being configured to stabilize and/or fix the imaging unit (2) in a position and/or orientation in the object (5) by bringing the outer face (3a) of the position stabilizing structure (3) into contact with the object (5). The device (1) further comprises a processing unit (4) configured to generate an optoacoustic image (23b) of the region of interest (7) based on the detection signals.
