Imaging technology plays an important role in the diagnosis, treatment and monitoring of diseases. As a new non-ionizing and non-invasive biomedical imaging technology, thermoacoustic imaging combines the advantages of microwave imaging high contrast and ultrasound imaging high resolution. Because of its ability to use endogenous contrast agents (such as water and ions) or multiple exogenous contrast agents (or both) to provide structure, function, and molecular information, it has been shown in pre-clinical and clinical applications. huge potential. In recent decades, due to the continuous development of microwave radiation sources and ultrasound hardware, thermoacoustic imaging technology has been widely used in the field of biomedical imaging. This article explains the basic principles and imaging characteristics of thermoacoustic imaging, introduces the application of thermoacoustic imaging technology in biomedicine in recent years, the current advantages and research status in solving corresponding clinical problems, and finally focuses on the current status of thermoacoustic imaging technology. There are challenges faced in biomedicine, and the technology is prospected. [ABSTRACT FROM AUTHOR]
