Abstract:Optical-resolution photoacoustic microscopy (OR-PAM) is a label-free and non-invasive technique for imaging blood vessel and hemoglobin oxygen saturation (sO2) of living animals in vivo, providing functional information for disease diagnosis. However, most state-of-the-art OR-PAM systems require bulky and costly pulsed lasers, which hinders their wide applications in clinical settings. Here, a reflection-mode low-cost photoacoustic microscopy system using two laser diodes (LDs) was developed for in-vivo microv… Show more
