Abstract
A multi-modal catheter combining at least NIRF and IVUs imaging channels used to reveal integrated biological and structural features of a lumen intravascularly imaged through flowing blood in vivo and corrected for distance-related attenuation and/or scattering parameters of in vivo blood to compensate for discovered overestimation of the degree of in-vivo-blood attenuation of NIRF signal Enhancing the sensitivity of detection of vascular injury and/or plaque deposition beyond the capability of a standalone IVUS imaging as a result of the use of such corrected catheter.
