Abstract
Photoacoustic tomography (PAT), also known as thermoacoustic or optoacoustic tomography, is a hybrid imaging technique that utilizes electromagnetic energy to probe tissue, coupled with acoustic detection principles [10,9,18,22]. When a short electromagnetic pulse (e.g., microwave or laser) is used to irradiate a biological tissue, the thermoacoustic effect results in the emission of acoustic signals that can be measured by use of wide-band ultrasonic transducers. The objective of PAT is to produce an image that represents a map of the spatially variant electromagnetic absorption properties of the tissue, from knowledge of the measured acoustic signals. Because a strong correlation exists between electromagnetic absorption in biological tissue and the pathological condition of the tissue [8,6], the information revealed by PAT may benefit a wide range of biomedical imaging applications.
