Abstract:
Microcirculation is closely related to occurrence and development of disease, so it is of significance in noninvasive imaging of microcirculatory structure and function in vivo.Photoacoustic imaging is one of the main techniques in microcirculation imaging, which has the characteristics of high contrast, high detection depth and high sensitivity to tissue function.A review of the literature showed that photoacoustic technique can noninvasively image and quantitatively measure microcirculatory structure, vasoconstriction and vasodilation, concentration of hemoglobin, oxygen saturation, blood velocity and direction, oxygen metabolism level in a certain depth of living tissue in real time.Research progress in photoacoustic imaging of microcirculation in subcutis, cerebral cortex, tumor, eye and other tissues is reviewed in this paper.
