A new non-invasive technique has been proposed that uses light to examine the depths of the body
To this end, the research team led by Professor Jin Zhehong and Dr.
The researchers used a contrast agent based on surfactant-stripped semiconducting polymer (SSS) micelles and a 1064 nm laser to successfully demonstrate the in vivo imaging depth of the rat’s intestines and bladder up to 5.
The principle of PA imaging is that the instantaneous thermal expansion generated by the imaging acoustic wave (photoacoustic) signal absorbs light and the ultrasonic sensor
The research of PA contrast agent is progressing smoothly, this kind of contrast agent can make the image of the deep organs of the human body more detailed
To this end, the researchers removed the surfactant from the semiconducting polymer micelles (this micelle can strongly absorb light with a wavelength of 1064 nanometers) and used it as a PA contrast agent
Unlike computed tomography (CT) that uses radiation, the PA imaging technology developed by Professor Jin's group can help diagnose deep tissue diseases without risk of exposure
Professor Jin Zhehong explained: "This study successfully imaged the deepest part of the human body (maximum depth of 5.
