Abstract

Nerve imaging in radical prostatectomy would facilitate nerve-sparing surgery. Nerve imaging can be performed with photoacoustic (PA) imaging and voltage-sensitive dyes (VSD), as demonstrated in [Kang, 2019] for brain neural activity. Continuous-wave (CW) PA was used to image dynamic targets, e.g., flow [Zhao, 2021], by firing multiple modulated exciters at the same time. However, CWPA has not been investigated with clinical transducers for prostate applications. We report here the development of such a dual-wavelength laser diode-based system and experimental results. We differentiate the acoustic signals resulting from each laser to provide fast and simultaneous spectral image.
