摘要

5 A SYSTEM, METHOD, AND LUMINESCENT MARKERFOR IMPROVED DIFFUSE LUMINESCENT IMAGING OR TOMOGRAPHY IN SCATTERING MEDIA 10 A method and system for luminescence molecular imaging or tomography of aregion of interest in a scattering medium is disclosed. The system comprises a non linear luminescent marker material arranged in the scattering medium. Contrast and resolution of the imaging or tomography is thus improved. The non-linear marker is for instance configured to upconvert incoming light of an illumination wavelength. The15 non-linear power dependence of the marker enables further improvement of the imaging by using images taken with two or more excitation beams simultaneously.: Fig. 920
