Abstract
A system and method are presented for use in angiographic imaging. The system comprises: a light source unit, and at least one imaging unit comprising a detector array, wherein the detector array comprises at least first and second types of detector cells having corresponding first and second different spectral response functions defining respectively first and second spectral peaks; and the light source is unit configured for emitting light formed of at least first and second discrete wavelength ranges which are selected to be aligned with said first and second spectral peaks of said first and second types of detector cells.
Claims20
A system, comprising:
- a light source unit;
- at least one imaging unit comprising a detector array, wherein the detector array comprises at least first and second types of detector cells having corresponding first and second different spectral response functions defining respectively first and second spectral peaks;
- and
- a light source unit configured for emitting light forming illumination including at least first and second discrete wavelength ranges, said at least first and second discrete wavelength ranges being aligned with said first and second spectral peaks of said first and second types of detector cells.
A method for acquiring image of biological tissue, the method comprising:
- providing image data, which corresponds to a light response of a region of interest to illumination of at least first and second different wavelength ranges, and is collected by a detector array comprising at least first and second different types of detector cells having corresponding first and second different spectral response functions defining respectively first and second spectral peaks aligned with said at least first and second different wavelength ranges, respectively;
- processing said image data by extracting therefrom at least first and second image data pieces associated with the collected light response by said at least first and second different types of detector cells, and
- generating output data indicative of an image map in accordance with a relation between said at least first and second image data pieces, said image map thereby providing enhanced contrast image of the region of interest.
