Abstract

Photoacoustic imaging is of great significance for the diagnosis and treatment of cardiovascular diseases because of its unique imaging principle, function and resolution. In this paper, we systematically introduced the principle and applications of photoacoustic blood flow velocity measu rement under three principles of photoacoustic Doppler, photoacoustic microimaging and photoacoustic correlation spectrum to provide some reference for researchers in this field.
