Fiber endface photoacoustic generator for quantitative photoacoustic tomography
Optics Letters, 2021 We demonstrate a novel fiber endface photoacoustic (PA) generator using infrared (IR) 144 laser dye dispersed within an ultraviolet adhesive. The generator provides a wide acoustic bandwidth in the transducer frequency range of 2–7 MHz, high thermal conversion efficiency ( > 90 % ), good PA signal controllability (well ...

Neurovascular photoacoustic tomography [PDF]
Frontiers in Neuroenergetics, 2010 Neurovascular coupling refers to the relationship between neuronal activities and downstream hemodynamic responses. Photoacoustic tomography (PAT), enabling comprehensive label-free imaging of hemodynamic activities with highly scalable penetration and spatial resolution, has great potential in the study of neurovascular coupling.
