Abstract
A photoacoustic (PA) sensor employs a linear deployment of an illumination source and a corresponding ultrasonic receiver for defining an imaging plane for rendering a PA image of a surgical or diagnostic region. A pair of illumination sources emanates from cladding removal of respective optical fibers, and irradiates in alignment with a side firing ultrasonic (US) array for receiving the induced PA signals. The US array extends longitudinally and parallel to the illumination sources, and an overlap of the respective irradiation regions extends from the illumination sources lies within a sensing region of the US array for defining an imaging plane captured by the US sensor for rendering on a visual device, often in conjunction with an ablation antenna or diagnostic probe for providing concurrent imaging during a surgical procedure.
