Adjustable photoacoustic tomography probe improves light delivery and image quality

open access: yesPhotoacoustics, 2018
One cause for suboptimal photoacoustic tomography (PAT) penetration depth is attenuation of incident light by soft tissue. To better understand this problem, we investigated the effects of illumination fiber optic bundle geometry on PAT penetration depth
