Principles of Photoacoustics: A Symphony of Light and Sound

Photoacoustics is built upon a fascinating principle where light, upon interaction with tissue, generates ultrasound waves. This phenomenon occurs when light energy is absorbed by tissue molecules, causing thermal expansion. The resulting pressure waves are detected and analyzed to provide detailed information about the tissue's structure, function, and molecular composition.

Margaret Campbell Barnes eloquently explains the underlying principles of photoacoustics, delving into the optical and acoustic properties of tissues, the generation and detection of photoacoustic signals, and the quantitative analysis of the data. She provides a thorough understanding of the factors influencing photoacoustic imaging, empowering readers to grasp the capabilities and limitations of this technique.
