Having six patents in hand and ten more pending, as well as more than 250 scientific papers in well-known journals, and also conference reports, Jacques de Guise is without contest an international leader in biomedical imagery.  With a multidisciplinary team made up of engineers and orthopaedic surgeons, he is the originator of, among other things, concrete medical tools. He is proud of his partnerships and he has developed, jointly with the Laboratoire Biomécanique de Paris, the EOS biplane imagery system, which uses 10 times less X-rays. Another of his achievements, and a product which is currently marketed, the KneeKG, offers totally new 3D imaged signature of the knee. Jacques de Guise can quite certainly boast that he has now attained a major business objective, that of being useful to society! He also serves society as a Professor at l'École de technologie supérieure.
