  Explore Thieme May 14 2019 Otolaryngology
  
  Introduction: The endoscopic optical coherence tomography (eOCT) allows the direct, contactless representation and evaluation of the morphology and oscillation behaviour of the tympanic membrane and adjoining tympanic cavity content. After further development of the measuring technology, the eOCT will be able to be used in vivo for the assessment of tympanoplasty results. Materials and Methods: The eOCT was applied to 10 patients after a tympanoplasty with an intact ossicular chain ...

3. Endoscopic Optical Coherence Tomography in Diagnostics of Otosclerosis
  
  Explore Thieme May 14 2019 Otolaryngology
  
  Introduction: Endoscopic Optical Coherence Tomography (eOCT) enables both high-resolution contact-free 3D-imaging of the tympanic membrane and spatial and frequency-resolved oscillation measurement via Doppler-OCT. Thus it is possible to detect causes of conduction hearing loss. In case of otosclerosis, changes in oscillation amplitude at the umbo had been showed via Laser-Doppler-Vibrometry. Material and Methods: The eOCT system utilizes a swept source laser with a wave length around 1300nm. Field-of-view and working ...

7. Visualization of interfacial adhesive defects at dental restorations with spectral domain and polarization sensitive optical coherence tomography
  
  Explore Home Oct 2 2018 Dentistry
  
  Restoration loss based on interfacial adhesive defects and associated caries at the restoration margin are the main causes for invasive replacement of dental restorations. Assessment of the interfacial quality based on clinical inspection and radiographic examination is often difficult and not reliable. In this work, we present spectral domain optical coherence tomography (SDOCT) and polarization sensitive optical coherence tomography (PSOCT) for the evaluation of tooth-composite bond failure. Imaging of two ...

  Explore Home - Springer Aug 23 2018 NDE/NDT , Textbooks
  
  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 samples. Because of the rapid enhancement of OCT with respect to acquisition speed and axial resolution over the past years, OCT is becoming more and more attractive for applications in nondestructive testing and evaluation. In this chapter, a brief introduction to the technique and ...

9. A System for Clinical Use of Endoscopic Optical Coherence Tomography
  
  Explore Thieme May 1 2018 Otolaryngology , Probes
  
  Introduction: Optical Coherence Tomography (OCT) allows non-invasive high-resolution imaging of tissues. With a penetration depth of a few millimeters it's possible to image the tympanic membrane and the close-by part of the tympanum, e.g. for diagnostics of otitis media and middle ear effusion. In the field of in vivo examination there are difficulties in access to the human tympanic membrane due to the narrow and curved external ear ...

  Explore SPIE Digital Library Mar 20 2018 Cardiology
  
  The mechanical components of the heart, especially the valves, are enormously stressed during lifetime and undergo different pathophysiological tissue transformations, which affect cardiac output and in consequence living comfort of affected patients. Calcific aortic valve stenosis (AVS) is the most common valve disease in modern industrial countries but the pathogenesis and progression of this disease is still unknown. Therefore, animal models, especially mouse models, are a powerfull tool to investigate ...

12. In vivo imaging in the oral cavity by endoscopic optical coherence tomography
  
  Explore SPIE Digital Library Mar 8 2018
  
  The common way to diagnose hard and soft tissue irregularities in the oral cavity is initially the visual inspection by an experienced dentist followed by further medical examinations, such as radiological imaging and/or histopathological investigation. For the diagnosis of oral hard and soft tissues, the detection of early transformations is mostly hampered by poor visual access, low specificity of the diagnosis techniques, and/or limited feasibility of frequent screenings ...

  As dental caries is one of the most common diseases, the early and noninvasive detection of carious lesions plays an important role in public health care. Optical coherence tomography (OCT) with its ability of depth-resolved, high-resolution, noninvasive, fast imaging has been previously recognized as a promising tool in dentistry. Additionally, polarization sensitive imaging provides quantitative measures on the birefringent tissue properties and can be utilized for imaging dental tissue, especially ...

  Since optical coherence tomography (OCT) provides three-dimensional high-resolution images of biological tissue, the benefit of polarization contrast in the field of dentistry is highlighted in this study. Polarization-sensitive OCT (PS OCT) with phase-sensitive recording is used for imaging dental and mucosal tissues in the human oral cavity in vivo . An enhanced polarization contrast of oral structures is reached by analyzing the signals of the co- and crosspolarized channels of the ...

  The structure of domain walls (DW) in ferroelectric media is of great interest as this material is used for frequency doublers and other applications. We show that the structure of the DWs can nicely be visualized by high resolution optical coherence tomography (OCT). While the high group refractive index of lithium niobate allows a resolution much better than 1 m, the large dispersion can blur the image and has to ...

  Abstract In this paper, we present a reliable and robust method for magnetomotive optical coherence tomography (MM-OCT) imaging of single cells labeled with iron oxide particles. This method employs modulated longitudinal and transverse magnetic fields to evoke alignment and rotation of anisotropic magnetic structures in the sample volume. Experimental evidence suggests that magnetic particles assemble themselves in elongated chains when exposed to a permanent magnetic field. Magnetomotion in the intracellular ...
