Definition
A technique for creating detailed cross-sectional or three-dimensional images of the interior of an object, such as the human body, by scanning it with waves or radiation.

In the news
The article discusses 'photoacoustic tomography,' a specific medical imaging method that converts laser light into sound waves to map internal structures without using harmful radiation. It serves as the core technology being evaluated for its ability to provide deep-tissue diagnostic images.
