1. Mechanical compression for biotissue image enhancement in optical coherence tomography

   Explore Article SPIE Digital Library (Feb 11 2010)

   The paper discusses application of mechanical compression for contrasting structural components of biotissues with different mechanical properties in optical coherence tomography (OCT) images. Ex vivo study on human rectum samples and in vivo study on human thin skin samples are performed. It is shown that for ex vivo sample the contrast between epithelial and stroma layers increases with increase in applied pressure. For in vivo sample it is shown that at weak constant applied pressure the contrast between epidermal and dermal layer increases exhibiting maximum after 2-3 minutes since pressure application. Monte Carlo simulations of OCT images of human rectum ... (Read Full Article)

   The efficiency of the mechanical compression of biotissues for improving the differentiation between pathological changes in the structure of a biotissue observed by the method of optical coherence tomography (OCT) is investigated. The effect of the compression in the OCT-images of samples of the human rectum affected by inflammation and carcinoma is studied ex vivo. It is shown that the use of compression makes it possible to differentiate between these pathological changes. To interpret experimental data, images of an inflamed part of rectum are modeled by the Monte Carlo method for different degrees of compression. The results of modeling agree ...

   Dynamics of nanoparticles penetrating and accumulating in healthy (skin) and pathologically altered (tumor) tissue was investigated in vivo by the method of optical coherence tomography (OCT). Gold nanoshells having the size of 130/15 nm and titanium dioxide nanoparticles 40-100 nm in size were stud ... [Proc. SPIE 7188, 71880L (2009)] published Mon Feb 16, 2009. (Read Full Article)

4. Contrasting properties of gold nanoparticles for optical coherence tomography: phantom, in vivo studies and Monte Carlo simulation

   Explore Article Institute of Physics (Aug 17 2008)

   Abstract. The possibility of using silica–gold nanoshells with 150 nm silica core size and 25 nm thick gold shell as contrasting agents for optical coherence tomography (OCT) is analyzed. Experiments on agar biotissue phantoms showed that the penetration of nanoshells into the phantoms increases the intensity of the optical coherence tomography (OCT) signal and the brightness of the corresponding areas of the OCT image. In vivo experiments on rabbit skin demonstrated that the application of nanoshells onto the skin provides significant contrasting of the borders between the areas containing nanoshells and those without. This effect of nanoshells on skin in ... (Read Full Article)
