    photoacoustic
    Photoacoustic refers to the generation of acoustic (sound) waves following the absorption of light (usually laser pulses) by a material. This phenomenon occurs when light energy is absorbed by a material, leading to localized heating and subsequent thermal expansion, which generates pressure waves (sound waves) that can be detected using ultrasonic sensors. The photoacoustic effect is utilized in various scientific and medical applications, including: Photoacoustic imaging (PAI): A...
    photoacoustic imaging
    Abbreviated PAI. An imaging modality with a hybrid technique based on the acoustic detection of optical absorption from endogenous chromophores or exogenous contrast agents. Light is absorbed by the chromophores and converted into transient heating, and through thermoelastic expansion there is a resulting emission of ultrasonic waves. In tissue, ultrasound scatters less than light, therefore PAI generates high-resolution images in the diffusive and optical ballistic regimes compared to purely...
