Calibration for OCT-NIRAF multimodality probe
A multimodality system includes first and second modalities, a catheter, and a processor. The catheter collects fluorescent light from a plurality of locations of a sample which has been irradiated with excitation light of the second modality; a detector detects intensity of the fluorescent light received from the plurality of locations as a function of an angle .alpha. formed between the normal to the sample surface and the optical axis of the excitation light. A processor calculates the angle .alpha. at each of the plurality of locations based on radiation of the first modality incident on the sample, and corrects ...
