Development of full-field optical spatial coherence tomography system for automated identification of malaria using the multilevel ensemble classifier.

abstract：:Photoacoustic microscopy (PAM) is a noninvasive imaging technique and is excellent to study structural and functional changes in the microcirculation. In this work, a lipopolysaccharide (LPS)-induced inflammation model in mice is noninvasively evaluated by PAM. PAM is used to image the microvascular structural changes...
