Detail

Product Principles

   

Optoacoustic imaging is an emerging noninvasive hybrid imaging technology that combines optical excitation and ultrasonic detection. During the imaging process, the optoacoustic contrast agent absorbs a non-ionizing pulse laser and converts it into heat, which generates sound waves through thermoelastic expansion. These sound waves are detected using broadband ultrasonic transducers and optoacoustic images can be constructed according to the arrival time of the sound waves. Compared with photons, phonons scatter less in biological tissues, so optoacoustic imaging has the advantages of high tissue contrast, high spatial resolution and deep imaging. Compared with traditional near infrared region I (NIR- I,600-900 nm) optoacoustic imaging, the near infrared region II (NIR- II, 900-1700 nm) optoacoustic imaging showed higher penetration and lower tissue absorption and scattering.
