This framework achieved a root mean square error of 10. 2 m/s and 15. 2 m/s for SoS estimation on digital and physical phantoms, respectively and structural similarity index measures of up to 0. 86 for PA reconstructions as compared to the conventional approach of 0. 69.

However, PA signals generated with these light sources are readily degraded by noise due to the low optical fluence, leading to decreased signal-to-noise ratio (SNR) in PA images.
