TomoWave technology employs the principles of depth-resolved optoacoustic (photoacoustic or thermoacoustic) imaging. Laser Optoacoustic Imaging System illuminates tissues by short laser pulses with dark red color.

Absorption of laser energy specifically by tissue molecules selected by the wavelength of laser light increases tissue temperature to a small fraction of one degree, simultaneously generating local pressure.

Thermal expansion of the heated voxels of tissue launches acoustic pressure waves (ultrasound). Detection of ultrasound signals from multiple positions of the detector (transducer) and conversion of these signals into a digital form allows the acquisition and storage of quantitative information about the object of interest. 

The computer is used to reconstruct tomography images of molecular contact and tissue function, thereby providing diagnostics of cancer and vascular diseases
