TomoWave NIR-I & NIR-II In vivo 3D Optoacoustic Imaging System

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.

Product Characteristics
The LOIS-3D system can achieve NIR-I & NIR-II optoacoustic imaging effects because its excitation wavelength can reach 660-2300 nm. It can perform 2D and 3D imaging of the biological characteristics of living animals and obtain qualitative and quantitative data, providing more accurate diagnostic analysis for drug targeted therapy, early tumor screening, cardiovascular disease and brain disease monitoring and other research.
