    2. The diagnosis of nasopharyngeal carcinoma by optical coherence tomography (OCT)

      The diagnosis of nasopharyngeal carcinoma by optical coherence tomography (OCT)
      We have attempted to explore the intrinsic differences in the optical properties of the nasopharyngeal carcinoma (NPC) and normal tissue by optical coherence tomography (OCT). OCT imaging of normal tissue provided three layers of epithelium, lamina propria, and the brighter interface of basement membrane; while carcinomas disrupted the layered construction embedded in signal-poor images. The morphologies were consistent with histological findings. Sensitivity and specificity were 90% and 100%, respectively. This ...

    3. Optically integrated trimodality imaging system: combined all-optical photoacoustic microscopy, optical coherence tomography, and fluorescence imaging

      Optically integrated trimodality imaging system: combined all-optical photoacoustic microscopy, optical coherence tomography, and fluorescence imaging
      We have developed a trimodality imaging system by optically integrating all-optical photoacoustic microscopy (AOPAM), optical coherence tomography (OCT), and fluorescence microscopy (FLM) to provide complementary information including optical absorption, optical back-scattering, and fluorescence contrast of biological tissue. By sharing the same low-coherence Michelson interferometer, AOPAM and OCT could be organically optically combined. Also, owing to using the same laser source and objective lens, intrinsically registered photoacoustic and fluorescence signals are ...

    4. Polyaniline nanoparticles: potential optical coherence tomography contrast agents

      Polyaniline nanoparticles: potential optical coherence tomography contrast agents
      Polyaniline, an organic conducting polymer, exhibits strong light absorption in the near-infrared region. Herein, the potential of polyaniline nanoparticles as the contrast agents for optical coherence tomography imaging was investigated. Polyaniline nanoparticles were synthesized by a facile chemical oxidative method. The optical coherence tomography images obtained from ex vivo swine liver tissues showed the concentration-dependent contrast effect of polyaniline nanoparticles. Then the nanoagents were applied to in vivo optical coherence ...

      Effects of titanium dioxide nanoparticles coupled with diode laser on optical properties of in vitro normal and cancerous human lung tissues studied with optical coherence tomography and diffuse reflectance spectra
      The objective is to investigate the effects of two different sized (60 and 100 nm) titanium dioxide ( TiO 2 ) nanoparticles (NPs) penetration and accumulation in in vitro human normal lung (NL) tissue, lung squamous cell carcinoma (LSCC) tissue, and 650-nm diode laser-pretreated tissue on their optical properties studied with optical coherence tomography monitoring and diffuse reflectance (DR) spectra measurement. As with TiO 2 NPs penetrating into the tissues, the intensities ...

    6. Influence of nanoparticles accumulation on optical properties of human normal and cancerous liver tissue in vitro estimated by OCT

      Influence of nanoparticles accumulation on optical properties of human normal and cancerous liver tissue in vitro estimated by OCT
      In this work, the potential use of nanoparticles as contrast agents by using spectral domain optical coherence tomography (SD-OCT) in liver tissue was demonstrated. Gold nanoparticles (average size of 25 and 70nm), were studied in human normal and cancerous liver tissues in vitro , respectively. Each sample was monitored with SD-OCT functional imaging for 240min. Continuous OCT monitoring showed that, after application of gold nanoparticles, the OCT signal intensities of normal ...

    7. Monitoring of permeability of different analytes in human normal and cancerous bladder tissues invitro using optical coherence tomography

      Monitoring of permeability of different analytes in human normal and cancerous bladder tissues invitro using optical coherence tomography
      We report our preliminary results on quantification of glucose and dimethyl sulfoxide (DMSO) diffusion in normal and cancerous human bladder tissues in vitro by using a spectral domain optical coherence tomography (SD-OCT). The permeability coefficients (PCs) of a 30% aqueous solution of glucose are found to be (7.92 0.81) 10 -6 cm s -1 and (1.19 0.13) 10 -5 cm s -1 in normal and cancerous ...

      Influence of different sized nanoparticles combined with ultrasound on the optical properties of invitro normal and cancerous human lung tissue studied with OCT and diffuse reflectance spectra
      The present study is concerned with the in vitro study of different sized titanium dioxide (TiO 2 ) nanoparticles' (NPs) penetration and accumulation in human normal lung (NL) tissue and lung adenocarcinoma tumor (LAT) tissue by the methods of continuous optical coherence tomography (OCT) monitoring and diffuse reflectance (DR) spectra measurement, and their evaluating the effects of TiO 2 NPs in two sizes (60nm and 100nm) and their combination with ultrasound ...

    10. Effect of differently sized nanoparticles' accumulation on the optical properties of ex vivo normal and adenomatous human colon tissue with OCT imaging and diffuse reflectance spectra

      Effect of differently sized nanoparticles' accumulation on the optical properties of ex vivo normal and adenomatous human colon tissue with OCT imaging and diffuse reflectance spectra
      Using optical coherence tomography (OCT) and diffuse reflectance spectra, we investigated the dynamics of titanium dioxide (TiO 2 ) nanoparticles, of different sizes, when penetrating and accumulating in human normal colon tissue (NC) and adenomatous colon tissue (AC). The process of nanoparticle penetration and accumulation in biotissue is accompanied by changes in the optical properties of tissue. Continuous OCT monitoring showed that, after application of TiO 2 nanoparticles, the OCT signal ...

      In vitro study of the effects of ultrasound-mediated glycerol on optical attenuation of human normaland cancerous esophageal tissues with optical coherence tomography
      Previous studies from our group have demonstrated that glucose solution can induce optical clearing enhancement of esophageal tissues with optical coherence tomography (OCT). The aims of this study were to evaluate the optical clearing effects of ultrasound-mediated optical clearing agents (OCAs) and to find more effective methods to distinguish human normal esophageal tissues (NE) and cancerous esophageal tissues (CE). Here we used the OCT technique to investigate the optical attenuation ...

    13. Investigation of the permeability and optical clearing ability of different analytes in human normal and cancerous breast tissues by spectral domain OCT

      Investigation of the permeability and optical clearing ability of different analytes in human normal and cancerous breast tissues by spectral domain OCT
      The potential of OCT applied for early breast cancer detection attracted significant efforts. The permeability coefficients and the percentages of OCT signal enhancement for normal and cancerous breast tissues have been investigated from the experiments of 20% glucose, 40% glucose, and 20% mannitol in vitro. Obtained results indicate that the permeability coefficient in breast cancer tissue is prominently larger than that in normal breast tissue, while the optical clearing effect ...
