Contrast Enhancement of Optical Coherence Tomography Images Using Branched Gold Nanoparticles
Figure 4
(a) Characteristic OCT B-scan image of tissue phantom with and without B-GNPs. (b) OCT B-scan image of tissue phantom showing the corresponding zones used to calculate contrast enhancement (white squares). (c) Average A-scan of tissue phantom without B-GNPs is represented by the dotted line, while average A-scan of tissue phantom with B-GNPs is represented by the continuous line. Inset: zoom of the profile corresponding to the depth of the layer with nanoparticles (signaled by the arrow) showing the enhancement of backscattered light.
