    2. Endoscopic optical coherence tomography for imaging the tympanic membrane

      Endoscopic optical coherence tomography for imaging the tympanic membrane
      Optical coherence tomography (OCT) is an imaging modality that enables micrometer-scale contactless subsurface imaging of biological tissue. Endoscopy, as another imaging method, has the potential of imaging tubular organs and cavities and therefore has opened up several application areas not accessible before. The combination of OCT and endoscopy uses the advantages of both methods and consequently allows additional imaging of structures beneath surfaces inside cavities. Currently, visual investigations on the ...

    3. Optical coherence tomography in biomedical research

      Optical coherence tomography in biomedical research
      Optical coherence tomography (OCT) is a noninvasive, high-resolution, interferometric imaging modality using near-infrared light to acquire cross-sections and three-dimensional images of the subsurface microstructure of biological specimens. Because of rapid improvement of the acquisition speed and axial resolution of OCT over recent years, OCT is becoming increasingly attractive for applications in biomedical research. Therefore, OCT is no longer used solely for structural investigations of biological samples but also for functional ...

    4. Non-invasive imaging and monitoring of rodent retina using simultaneous dual-band optical coherence tomography

      Non-invasive imaging and monitoring of rodent retina using simultaneous dual-band optical coherence tomography
      Spectral domain dual-band optical coherence tomography for simultaneous imaging of rodent retina in the 0.8 μm and 1.3 μm wavelength region and non-invasive monitoring of the posterior eye microstructure in the field of retinal degeneration research is demonstrated. The system is illuminated by a supercontinuum laser source and allows three-dimensional imaging with high axial resolution better than 3.8 μm and 5.3 μm in tissue at 800 ...

    5. Three-dimensional functional imaging of lung parenchyma using optical coherence tomography combined with confocal fluorescence microscopy

      Three-dimensional functional imaging of lung parenchyma using optical coherence tomography combined with confocal fluorescence microscopy
      Optical coherence tomography (OCT), as a non-invasive technique for studying tissue morphology, is widely used in in vivo studies, requiring high resolution and fast three-dimensional imaging. Based on light scattering it reveals micrometer sized substructures of the samples due to changes in their optical properties and therefore allows quantification of the specimen's geometry. Utilizing fluorescence microscopy further information can be obtained from molecular compositions embedded in the investigated object ...

    8. Optical coherence tomography as approach for the minimal invasive localization of the germinal disc in ovo before chicken sexing

      Optical coherence tomography as approach for the minimal invasive localization of the germinal disc in ovo before chicken sexing
      In most industrial states a huge amount of newly hatched male layer chickens are usually killed immediately after hatching by maceration or gassing. The reason for killing most of the male chickens of egg producing races is their slow growth rate compared to races specialized on meat production. When the egg has been laid, the egg contains already a small disc of cells on the surface of the yolk known ...

    9. Combining optical coherence tomography with fluorescence microscopy: a closer look into tissue

      Combining optical coherence tomography with fluorescence microscopy: a closer look into tissue
      Optical coherence tomography (OCT) is a technique, capable of high resolution and non-invasive 3D imaging in vivo by detection of backscattered light from cellular and sub cellular structures. Due to visualization of micrometer sized tissue constituents and high penetration depths of up to 2 mm, it is already well established in medical fields like ophthalmology and dermatology. Laser scanning confocal microscopy (LSCM), on the contrary, gives further information on structural ...

    10. Minimal invasive localization of the germinal disc in ovo for subsequent chicken sexing using optical coherence tomography

      Minimal invasive localization of the germinal disc in ovo for subsequent chicken sexing using optical coherence tomography
      Reason for using optical coherence tomography (OCT) to locate the germinal disc is the questionable and ethically alarming killing of male layer chickens because for the layer line only the females are necessary. To avoid this and to protect the animal rights, the sex of the fertilized chicken egg has to be determined as early as possible in the unincubated state. Because the information whether the chick becomes male or ...

    11. Investigations of the intravascular backscattering distribution of light in optical coherence tomography

      Investigations of the intravascular backscattering distribution of light in optical coherence tomography
      The inhomogeneous backscattering distribution of low-coherent light in blood vessels, which appears as waisted double fan-shaped intensity pattern, is investigated in an in vivo mouse model and flow phantom measurements using high resolution spectral domain optical coherence tomography in the 1.3 m wavelength region. Based on a predicted orientation of the red blood cells towards laminar flow, an angular modulation of the corresponding backscattering crosssection inside the vessels is ...

    13. Doppler Fourier Domain Optical Coherence Tomography: A Novel Technique to Analyze Exercise-dependent Changes in Vascular Dynamics of Wild-type and LDL Receptor Knockout Mice in vivo

      Regular exercise is beneficial for the prevention of endothelial dysfunction and atherosclerosis. However, the measurement of changes in vascular dynamics in murine models in vivo is difficult. Therefore, we developed a novel Doppler FD OCT device allowing determination of blood flow in murine arteries and veins with a spectrum read out rate of 12 kHz. The high temporal resolution of the system can be used to quantify the pulse from ...

  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.
