    2. Transverse and oblique motion effects in Fourier Domain Optical Coherence Tomography

      In this study we describe the effects on the interference signal caused by transverse and oblique motion in spatially encoded Fourier Domain Optical Coherence Tomography (FD OCT). The artifacts caused by sample motion were analyzed theoretically and experimentally. The presented results supply an understanding of the SNR degradation caused by sample motion and demonstrates the importance of fast data acquisition in medical imaging.

    3. Three-dimensional Imaging of subpleural Alveoli by Fourier Domain Optical Coherence Tomography

      Understanding alveolar mechanics is essential to improve artificial ventilation strategies and hence minimize ventilator associated lung injury. The investigation of alveolar geometry changes during ventilation was performed by intravital microscopy (IVM) and 3D Fourier domain optical coherence tomography (3D-OCT) in an in-vivo mouse model and in isolated, perfused and ventilated rabbit lungs. Air pocket size of individual alveoli was quantified in the en-face view. For both imaging techniques, IVM and ...

    4. Fabrication of thin and flexible PDMS membranes for biomechanical test applications

      For continuous analysis of mechanical properties of soft biological tissues during mechanical stimulation we developed a bioreactor to apply controlled periodic deflection to a probe. The probe attached on an elastic membrane produces a counterpressure if a certain gas volume is applied to the pressure chamber under the membrane. The related counterpressure-volume relationship describes the mechanical properties of the membrane-probe combination. To improve the signal-to-noise ratio of measurements the use ...

    5. Interferometric device

      The invention relates to an interferometric device according to the preamble ofthe main claim. Devices for optical coherence tomography (OCT) comprise an interferometer and an evaluating unit for the electronic detection of an interference pattern.Interferometers and methods for determining the transit time distribution of reflected or scattered light are known under the term "Optical Coherence Tomography (OCT)". For example, DE 199 29 406 A1 describe such a method for ...

    6. Optical Coherence Tomography (oct) A New Method For In Vivo Imaging And Quantification Of Collateral Vessel Growth In Mice

      Therapeutic augmentation of collateral vessel growth (arteriogenesis) is of particular clinical interest. Quantification of collateralization in small animal models is, however, difficult and the commonly used technique of Laser Doppler perfusion imaging (LDPI) has always been criticized, especially as determination of flow in the vascular system is infeasible. We hypothesized that the new technology of optical coherence tomography (OCT), a non-invasive high resolution tomography imaging technique, may constitute a valuable ...

    7. Effects of axial, transverse, and oblique sample motion in FD OCT in systems with global or rolling shutter line detector

      This study deals with effects on the interference signal caused by axial, transverse, and oblique motion in spectrometer-based Fourier-domain optical coherence tomography (FD OCT). Two different systems are compared--one with a global shutter line detector and the other with a rolling shutter. We ... [J. Opt. Soc. Am. A 25, 2791-2802 (2008)]

    8. 3D-X-ray micro computed tomography and optical coherence tomography as methods for the localization of the germinal disk in the newly laid unincubated chicken egg

      The routine culling of the male offspring of hybrid layer type chickens is met with increasing public disapproval for both ethical and legal reasons. Until now practice-oriented methods for reliable sex diagnosis prior to hatch could not be developed. Molecular genetical analysis of blastodermic cells can be used for sex determination in unincubated eggs; however, knowledge of the precise localization of the germinal disc is crucial for the extraction of ...

  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.
