    2. Brain tissue analysis using texture features based on optical coherence tomography images

      Brain tissue analysis using texture features based on optical coherence tomography images
      Brain tissue differentiation is highly demanded in neurosurgeries, i.e. tumor resection. Exact navigation during the surgery is essential in order to guarantee best life quality afterwards. So far, no suitable method has been found that perfectly covers this demands. With optical coherence tomography (OCT), fast three dimensional images can be obtained in vivo and contactless with a resolution of 1-15 m. With these specifications OCT is a promising tool ...

    3. Automated differentiation between meningioma and healthy brain tissue based on optical coherence tomography ex vivo images using texture features

      Automated differentiation between meningioma and healthy brain tissue based on optical coherence tomography ex vivo images using texture features
      Brain tissue analysis is highly desired in neurosurgery, such as tumor resection. To guarantee best life quality afterward, exact navigation within the brain during the surgery is essential. So far, no method has been established that perfectly fulfills this need. Optical coherence tomography (OCT) is a promising three-dimensional imaging tool to support neurosurgical resections. We perform a preliminary study toward in vivo brain tumor removal assistance by investigating meningioma, healthy ...

      Feature Of The Week 07/24/2017: Spectral Domain Optical Coherence Tomography for Non-Destructive Testing of Protection Coatings on Metal Substrates
      Industrial monuments and other artefacts of vanishing industries have to be preserved as cultural heritage. For example, in Germany next year the public subsidy for the mining industry will end and with this the active mining will end as well. The Deutsches Bergbau-Museum in Bochum as one of the largest of its kind and as a research institution of the Leibnitz association is committed to preserve the cultural heritage of ...

    5. Spectroscopic optical coherence tomography for ex vivo brain tumor analysis

      Spectroscopic optical coherence tomography for ex vivo brain tumor analysis
      For neurosurgeries precise tumor resection is essential for the subsequent recovery of the patients since nearby healthy tissue that may be harmed has a huge impact on the life quality after the surgery. However, so far no satisfying methodology has been established to assist the surgeon during surgery to distinguish between healthy and tumor tissue. Optical Coherence Tomography (OCT) potentially enables non-contact in vivo image acquisition at penetration depths of ...

      Feature Of The Week 10/10/10: Comparison of OCT, uCT, and Histology at 3D Imaging of Trabecular Bone Samples
      Feature Of The Week 10/10/10: Recently researchers from the Photonics and Terahertz Technology Group at Ruhr-University, the Experimental Orthopaedics and Biomechanics Department at Philipps University Marburg, the Division of Biomechanics and Engineering Design at Katholieke Universiteit Leuven, and the Department of Dermatology and Allergology at St. Josef Hospital in Bochum, Germany published a very interesting paper on the application of OCT to trabecular bone samples and compared those ...
