      Three-dimensional color camera based on optical coherence tomography

      We propose a 3D color camera to record the moving objects image based on optical coherence tomography (OCT). A precise surface topography map of the object is acquired by OCT, to which, a color image acquired by a CCD, is fused. During OCT scanning, adjacent color images are cross-correlated to compute the offset position of the moving object. The offset position is applied to the OCT to tracking scan the moving object. A 3D topography algorithm is to reconstruct surface topography maps. The affine transform and similarity model are used to match the 2D color image to the surface topography ...

    2. Three-Dimensional High-Resolution Imaging of Gold Nanorods Uptake in Sentinel Lymph Nodes

      Three-Dimensional High-Resolution Imaging of Gold Nanorods Uptake in Sentinel Lymph Nodes
      n this paper, we demonstrate an application of a noninvasive imaging modality, photothermal optical coherence tomography (PT-OCT), for imaging gold nanorods (GNRs) uptake in sentinel lymph node (SLN) of mice in situ. This application enables us to obtain higher quality images of SLN structures due to the photothermal contrast properties of the GNRs. It is also demonstrated that GNRs accumulate differently within several SLN structures, and this uptake is time dependent. Finally, we determine the average concentration of GNRs within the whole SLN which is used to demonstrate uptake kinetics of the nanoparticles.
