Through hundreds of publications and conference papers each year, photoacoustic imaging (PAI) has been shown to have potential for early detection of afflictions such as skin and thyroid cancer, cardiovascular disease, and arthritis. The noninvasive technique combines pulsed laser light for the excitation of tissues with an ultrasound transducer as a receptor. PAI penetrates much deeper than purely optical imaging technologies such as optical coherence tomography. It also offers far greater specificity than conventional ultrasound imaging. Figure 1.
