Photoacoustic Imaging Technology and Its Clinical Application to Breast Tumors

Photoacoustic imaging(PAI) based on the photoacoustic effect is a new and promising biomedical imaging technology. It has the advantages of high optical contrast and deep ultrasonic penetration. Furthermore, it has the ability to acquire functional information based on optical imaging with multi-wavelength. The application of PAI in breast tumors has been widely explored. In this article, we reviewed the PAI systems and their clinical application to breast tumors over the past few years and looked into the prospect of the application of PAI in the future.
