Photoacoustic imaging - Wikipedia
网页Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect. Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband (i.e. MHz) ultrasonic emission.

网页The aim of the open access Photoacoustics journal (PACS) is to publish original research and review contributions within the fast-growing field of photoacoustics-optoacoustics-thermoacoustics, which exploits acoustical and ultrasonic phenomena excited by electromagnetic radiation for purposes of detection, visualization, and characterization of ...
Photoacoustic effect - Wikipedia
网页The photoacoustic effect or optoacoustic effect is the formation of sound waves following light absorption in a material sample. In order to obtain this effect the light intensity must vary, either periodically (modulated light) or as a single flash (pulsed light).
