Photoacoustic imaging is an emerging hybrid imaging modality in the medical imaging sector which can provide multi-contrast, multiscale imaging and biological features ranging from organelles to organs. Different products are used in photoacoustic imaging such as imaging systems, contrast agents, and software, among others. Photoacoustic Imaging offer multiple advantages such as no harmful ionizing radiation, high image resolution, high penetration depth, near real-time imaging capability, excellent contrast agents and molecular targeting at imaging depth among others. Photoacoustic imaging is combined with ultrasound imaging to offer several advantages over other existing imaging modalities. 

Photoacoustic imaging works by using a pulsed laser to irradiate tissue. The light is absorbed by photo absorbers naturally present in tissue and contrast agents are added to tissue.  Contrast agents causes thermos-elastic expansion and then translates through the tissue as a pressure or acoustic wave. The acoustic waves are detected by an ultrasound transducer and then translated into an image of the location of the endogenous or exogenous contrast agents. The contrast in photoacoustic images depends primarily on how much light is absorbed by the tissue. The optical absorption of different materials varies with wavelength, and makes it possible to identify and distinguish between different tissue components using photoacoustic imaging.

Photoacoustic imaging finds its usage in various biomedical applications including deep tumor imaging, therapeutic responses monitoring, metabolic imaging, pH detection, enzyme detection, reactive oxygen species (ROS) detection, and metal ions detection among others. These are some of the major factors propelling the market growth for photoacoustic imaging. Photoacoustic imaging is integrated with optical imaging and ultrasound imaging, for rich contrast, high resolution and deep tissue penetration.  There are many types of medical imaging methods available in the market. The main types of imaging used in modern medicine include radiography, magnetic resonance imaging (MRI), nuclear medicine, and ultrasound among others. They are used for different circumstances for example, MRI scanners are used to take images of the brain or other internal tissues. Nuclear medicine is used to look inside the digestive or circulatory systems and ultrasound technique is used to look at foetuses in the womb and to take images of internal organs. Technological advancements and growing investment in development of capabilities of photoacoustic Imaging is expected to boost growth in the market.
