Ivan Gusachenko wins HORAO

The jury and audience selected the winning project at the HORAO Conference on
March 14, 2019. Ivan Gusachenko from Rennes, France, has won the global
crowdsourcing competition and therewith the prize money amounting to USD
$35,000. His promising proposed solution will now be further developed to
market maturity so that brain tumors can be operated even more safely in

Winner Ivan Gusachenko, Development Engineer at Cailabs SARL in Rennes,
France, proposes the use of «Optical Mueller Polarimetric Imaging» to visualize
brain tumors during surgery. «Mueller Polarimetry» uses polarized (i. e.
organized) light to probe the tissue structures. Organised structures in the
brain (brain fibres) reflect polarised light differently than unorganized cells

Gusachenko suggests equipping the surgical microscope with polarizers so that
tumor borders can be directly faded on the microscope image that the surgeon
sees during the surgery. With the prize money in the amount of USD 35,000 and
additional support by an expert coach, his project will be further advanced.
