Abstract

L'invention concerne des applications médicales de la technologie de formation d'images spectrales par polarisation croisée. Cette technologie permet d'obtenir une image à contraste élevé de phénomènes sub-superficiels tels que la structure d'un vaisseau sanguin, le flux sanguin dans les vaisseaux, la structure glandulaire, etc. ainsi qu'une image haute résolution de la surface des organes solides. De nombreuses applications cliniques (diagnostique et thérapeutique) ainsi que des applications de cette technologie dans la recherche, dans les domaines médical et pharmaceutique, font également l'objet de cette invention.
