Peripheral artery disease (PAD) is widespread among the elderly population where narrowing arteries in lower limbs are causing a lack of perfusion. This work explores the benefit of volumetric photoacoustic imaging (v-PAI) over conventional 2D PAI for PAD diagnosis and monitoring. To this end, we leverage the recently proposed approach of Tattoo tomography, which generates a v-PAI representation from a set of 2D PAI slices. Preliminary results of the ongoing study indicate that v-PAI can increase the sensitivity of early-stage PAD detection. Conclusively our Tattoo approach has the potential to become a valuable tool in PAD diagnostics.
