“…The tissue optical absorption image was generated using a square window corresponding to the time of flight of the acoustic signal through the glass slide. A tissue optical transmission image was generated using a square window in the PA signal trace, with a timing corresponding to the transducer response to light absorption in its surface [ 33 ]. Maximum intensity projection images were median filtered and convolved with a circular filter to account for the beam circular shape remapped to square pixels spatially.…”

Highlights We built a micro-spectroscopic photoacoustic imaging setup, allowing spectral imaging throughout the section. Spectral differences were primarily due to differences in hydrocarbon chain length and number of unsaturated bonds. PA signal intensity was most strongly correlated with sphingomyelin and cholesteryl ester area in MALDI-MSI. The spectral feature of lipids abundant in necrotic core can be used for detection of atherosclerosis with features of instability.
