    1. Optical coherence tomography device and method having improved boundary control and distortion correction

      Optical coherence tomography device and method having improved boundary control and distortion correction
      Variants of an interferometric device are developed for examining internal structures of objects by means of optical coherence tomography, which allow for controlling a boundary location of the observation range. The device also allows for correcting a distortion of the tomographic image of the object under study, caused by lateral scanning, due to aberrations of the optical path length for the low-coherence optical radiation directed towards the object. Embodiments of ...

    7. Application of optical coherence tomography in the diagnosis of mucositis in patients with head and neck cancer during a course of radio(chemo)therapy

      Objective Mucositis is the most common oral complication of non-surgical therapy (chemotherapy, radiotherapy, and radio(chemo)therapy) in patients with head and neck cancer. Growing evidence indicates that more aggressive treatment regimens improve local tumor control and the survival of patients with locally advanced head and neck cancer. However combined therapy approaches are associated with higher acute toxicity. Currently there are no in vivo methods to visualize microscopic changes of ...
