    2. Vibration of the human tympanic membrane measured with OCT in a range between 0.4 kHz and 6.4 kHz on an ex vivo sample

      Vibration of the human tympanic membrane measured with OCT in a range between 0.4 kHz and 6.4 kHz on an ex vivo sample
      Vibrations of the tympanic membrane (TM) play a key role for the transmission of sound to the inner ear. Today, there exist still problems in measuring the movement of the TM and there are unresolved issues in understanding the TM and its behavior. A non-invasive and contact-free in vivo investigation of the structure and the functional behavior of the TM would be a big step forward. In the presented study ...

    3. High-resolution optical coherence tomography in mouse models of genetic and induced retinal degeneration

      High-resolution optical coherence tomography in mouse models of genetic and induced retinal degeneration
      For the study of disease mechanisms and the development of novel therapeutic strategies for retinal pathologies in human, rodent models play an important role. Nowadays, optical coherence tomography (OCT) allows three-dimensional investigation of retinal events over time. However, a detailed analysis of how different retinal degenerations are reflected in OCT images is still lacking in the biomedical field. Therefore, we use OCT to visualize retinal degeneration in specific mouse models ...

    4. Magnetomotive imaging of iron oxide nanoparticles as cellular contrast agents for optical coherence tomography

      Magnetomotive imaging of iron oxide nanoparticles as cellular contrast agents for optical coherence tomography
      Recent studies in animal models provided proof-of-principle evidence for cell transplantation as a potential future therapeutic approach for retinal pathologies in humans such as Retinitis pigmentosa or age-related macular degeneration. In this case, donor cells are injected into the eye in order to protect or replace degenerating photoreceptors or retinal pigment epithelium. However, currently there is no three-dimensional imaging technique available that allows tracking of cell migration and integration into ...

    5. Four-dimensional optical coherence tomography imaging of total liquid ventilated rats

      Four-dimensional optical coherence tomography imaging of total liquid ventilated rats
      Optical coherence tomography (OCT) can be utilized for the spatially and temporally resolved visualization of alveolar tissue and its dynamics in rodent models, which allows the investigation of lung dynamics on the microscopic scale of single alveoli. The findings could provide experimental input data for numerical simulations of lung tissue mechanics and could support the development of protective ventilation strategies. Real four-dimensional OCT imaging permits the acquisition of several OCT ...

    6. Optical coherence tomography as a reference method for the detection of nanoparticles in thin-film polymer matrices

      Optical coherence tomography as a reference method for the detection of nanoparticles in thin-film polymer matrices
      In food and feed production an emerging issue is the use of nanoparticles as additives to control specific properties of the products. In this context, one focus in food chemistry is the development and evaluation of measurement techniques, which could allow the detection and quantification of nanoparticles in food products. For this purpose, special noninvasive and non-destructive reference methods are required, which allow subsequent analysis with other measurement techniques. Additionally ...

    7. Defense of fake fingerprint attacks using a swept source laser optical coherence tomography setup

      Defense of fake fingerprint attacks using a swept source laser optical coherence tomography setup
      The most established technique for the identification at biometric access control systems is the human fingerprint. While every human fingerprint is unique, fingerprints can be faked very easily by using thin layer fakes. Because commercial fingerprint scanners use only a two-dimensional image acquisition of the finger surface, they can only hardly differentiate between real fingerprints and fingerprint fakes applied on thin layer materials. A Swept Source OCT system with an ...

    8. A new small-package super-continuum light source for optical coherence tomography

      A new small-package super-continuum light source for optical coherence tomography
      Broadband light sources provide a significant benefit for optical coherence tomography (OCT) imaging concerning the axial resolution. Light sources with bandwidths over 200 nm result in an axial resolution up to 2 microns. Such broad band OCT imaging can be achieved utilizing super continuum (SC) light sources. The main important disadvantage of commercial SC light sources is the overall size and the high costs. Therefore, the use of SC light ...

    9. Investigation of the human tympanic membrane oscillation ex vivo by Doppler optical coherence tomography

      Investigation of the human tympanic membrane oscillation ex vivo by Doppler optical coherence tomography
      Investigations of the tympanic membrane (TM) can have an important impact on understanding the sound conduction in the ear and can therefore support the diagnosis and treatment of diseases in the middle ear. High-speed Doppler optical coherence tomography (OCT) has the potential to describe the oscillatory behaviour of the TM surface in a phase-sensitive manner and additionally allows acquiring a three-dimensional image of the underlying structure. With repeated sound stimuli ...

    10. An advanced algorithm for dispersion encoded full range frequency domain optical coherence tomography

      An advanced algorithm for dispersion encoded full range frequency domain optical coherence tomography
      Dispersion encoded full range (DEFR) optical coherence tomography (OCT) has become highly attractive as it is a simple way to increase the measurement range of OCT systems. Full range OCT is especially favorable as it does not only increase the measurement range but also shifts the highest sensitivity into the center of the measurement range. While the early versions of DEFR were highly computational expensive, new versions reduce the number ...

    11. Four-dimensional optical coherence tomography imaging of subpleural alveoli in mice

      Four-dimensional optical coherence tomography imaging of subpleural alveoli in mice
      The development of protective ventilation strategies for patients suffering from life-threatening lung diseases and the promotion of numerical simulation of lung tissue mechanics requires detailed knowledge about the three-dimensional alveolar micro-structure, their dynamics and elastic properties. Subpleural lung tissue can be observed in animal models utilizing optical coherence tomography (OCT) with a high spatial resolution. We present four-dimensional high-speed OCT imaging of single alveoli as a suitable technique for the ...

      A hybrid imaging system for simultaneous ophthalmic optical coherence tomography and dual-channel fluorescence detection in small animal models
      We present a novel hybrid system that allows simultaneous high-resolution spectral domain optical coherence tomography (OCT) in the near-infrared and single-photon excited fluorescence (SPEF) detection in the green and red visible wavelength range for non-invasive multimodal imaging of the retina in small in vivo animal models such as zebrafish.

  2. About Dresden University of Technology

    Dresden University of Technology

    Dresden University of Technology (Technische Universität Dresde) is the largest institute of higher education in the city of Dresden, the largest university in Saxony and one of the 10 largest universities in Germany with 34,993 students as of 2006. The name Technische Universität Dresden has only been used since 1961; the history of the university, however, goes back nearly 200 years to 1828. This makes it one of the oldest colleges of technology in Germany, and one of the country’s oldest Universitäten, which in German today refers to institutes of higher education which cover the entire curriculum. The university is member of TU 9, a consortium of the nine leading German Institutes of Technology.
