Abstract :
We analyze photoacoustic signals from capillaries and theoretically demonstrate the quantitative relationship between vascular diameter and spectral slope in a low-frequency band. Phantom experiments validate the theoretical analysis. Based on this finding, a spectrum-based photoacoustic microscopy is proposed.
