Abstract

The present disclosure relates to methods and systems relating to temperature dependent photoacoustic imaging are provided. In such methods and systems, a tissue sample may be exposed to thermal energy and electromagnetic radiation to generate an acoustic signal, which may be detected. The amplitude of the acoustic signal may be determined and correlated with a tissue property, such as the presence or absence of macrophages or foam cells.
