A photoacoustic medical imaging device may include a substrate, an array of ultrasonic transducers on the substrate, at least one groove etched on the substrate, at least one optical fiber, and at least one facet. Each optical fiber is disposed in one of the grooves. Each facet is etched in one of the grooves and coated with a layer of metal having high infrared reflectivity. Each optical fiber is configured to guide infrared light from a light source through the fiber and toward the respective facet. The facet is configured to reflect the infrared light toward a target.

L'invention concerne un dispositif d'imagerie médicale photo-acoustique pouvant comprendre un substrat, un réseau de transducteurs ultrasoniques sur le substrat, au moins un sillon gravé sur le substrat, au moins une fibre optique, et au moins une facette. Chaque fibre optique est disposée dans un des sillons. Chaque facette est gravée dans un des sillons et revêtue avec une couche métallique ayant une réflectivité infrarouge élevée. Chaque fibre optique est configurée pour guider une lumière infrarouge à partir d'une source de lumière, à travers la fibre et vers la facette respective. La facette est configurée pour réfléchir la lumière infrarouge vers une cible.
