Patent attributes
A perfusion assessment multi-modality optical medical device comprising⋅ a white light image sensor (320) and optical system configured to image a body area of interest (130, 340),a coherent light source (330) for illuminating said body area of interest with wavelength of 760-810 nm,an optical coherence imaging (OCI) image sensor (310) detecting the fluctuations of the backscattered light (302) near the illumination wavelength from at least part of said illuminated body area of interest (340),a fluorescence image sensor (315) to detect the fluorescence signal at higher wavelength than the illumination wavelength from at least part of said illuminated body area of interest (340),a screen (115, 210) to show the results from the modalities, all previous items being included in a single movable unit (200) which furthermore comprisesa processing unit (105, 110) to calculate perfusion map from the OCI image sensor (310) using LDI or LSI algorithms, wherein said white light image sensor (320), said OCI image sensor (310) and said fluorescence image sensor (315), at least partially, use a common optical path (610).
