    1. The use of optical coherence tomography for morphological study of scaffolds

      The use of optical coherence tomography for morphological study of scaffolds

      Aimed at possible widening of the optical coherence tomography (OCT) field of application, anattempt is made to use OCT in tissue engineering and cell transplantology as a tool formorphological studies of substrate materials by the example of scaffolds. By means of thetraditional fibreoptical OCT scheme the images of inner structure of scaffolds are obtained, andsimultaneously the spatial distribution of the intralipid flow velocity is reconstructed using theDoppler OCT. It is shown that combined use of traditional OCT and Doppler OCT schemes allowsrevealing the regions of the scaffold demonstrating optimal effect of shear stress, which is a key factor of cell ...

    2. Imaging of subcutaneous blood vessels and flow velocity profiles by optical coherence tomography

      Imaging of subcutaneous blood vessels and flow velocity profiles by optical coherence tomography

      We have applied a compact low power rapid scanning Doppler Optical Coherence Tomography system to monitor multi-dimensional velocity profiles within the complex vessels and simultaneous real-time non-invasive imaging of skin tissues morphology in vivo, in the wavelength range of 1.3–1.5 nm. Optical clearing of skin tissues has been utilized to achieve depth of OCT images up to 1.7 mm. Current approach enables applying low-power (0.4–0.5 mW) and low-noise broadband near-infrared light sources and obtaining OCT images with down to 12 μm spatial resolution. Two-dimensional time-domain OCT images of complex flow velocity profiles in ...

    3. Plant photonics: application of optical coherence tomography to monitor defects and rots in onion

      Plant photonics: application of optical coherence tomography to monitor defects and rots in onion
      The incidence of physiological and/or pathological defects in many fresh produce types is still unacceptably high and accounts for a large proportion of waste. With increasing interest in food security their remains strong demand in developing reliable and cost effective technologies for non-destructive screening of internal defects and rots, these being deemed unacceptable by consumers. It is well recognized that the internal defects and structure of turbid scattering media can be effectively visualized by using optical coherence tomography (OCT). In the present study, the high spatial resolution and advantages of OCT have been demonstrated for imaging the skins and ...

    4. Application of wavelet analysis in optical coherence tomography for obscured pattern recognition

      Application of wavelet analysis in optical coherence tomography for obscured pattern recognition

      Nowadays the optical coherent tomography (OCT) is one of the most perspective optical diagnostic modalities widely used for non-invasive imaging of the internal structure of various complex turbid media from a range of composite materials to biological tissues. OCT has been attracting a great amount of attention due to its effective capability rejecting multiple scattering. However, for highly scattered composite structures the multiple scattering still remains a factor limiting OCT to the quasiballistic regime. In order to enhance the OCT imaging capabilities and reduce the statistical noise associated with the multiple scattering the wavelet analysis has been applied. The wavelet ...

    5. Optical coherence tomography imaging depth enhancement by superficial skin optical clearing

      Optical coherence tomography imaging depth enhancement by superficial skin optical clearing
      Non-invasive imaging of human skin and human skin tissues by optical coherence tomography (OCT) is a field exciting a great deal of interest especially in terms of day-to-day medical and biomedical diagnostics.We develop rapid scanning OCT system for non-invasive real-time imaging of topical skin tissues in vivo. We investigate the possibility of OCT image enhancement along the transcutaneous diffusion into the skin an optical clearing agent. Diffusion of optical clearing agents, e.g. such as glycerol, temporary increases transparency of topical skin tissues that allows for unrestricted sounding radiation permeating deeper into the skin. Increasing transparency of superficial skin ...
