Purpose and goal
The project aims to develop a technology for optical imaging in tissue down to a depth of several centimeters. A company, Deep Light Vision AB, has been formed to further develop and commercialize the technology and two patents have been submitted. The method has been validated through comparisons between experiments and simulations. Data analysis methods are tested and further developed. Calculations indicate that our method has two orders of magnitude better contrast to noise than alternative optical deep tissue imaging methods.
Expected results and effects
The system has so far been developed for the wavelengths 690 nm and 793 nm. We believe this is an ideal wavelength combination for imaging oxygenation in tissue. The good results are a strong incentive to continue developing the method. Much work remains, but the most central question as to whether or not the method works, has been answered positively. There have also been no setbacks when it comes to method development or tests of concepts.
Planned approach and implementation
The project approach was primarily to perform experimental tests of the technology in parallel with the construction of a demonstrator. Major delays in deliveries resulted in that we were unable to carry out the planned experiments for a long time. In the meantime, we then expanded our work with modeling and data analysis. This has taken us much further ahead than expected in terms of modeling, but not as far as initially planned on the experimental side.
