  "country": "US",
  "title": "How to Create Wide-Field Images of Tissue Using OCT Scanners",
  "original_title": "System and method for generating a wide-field OCT image of a portion of a sample",
  "summary": "A method for stitching together multiple high-resolution medical images of uneven tissue samples to create a single, wide-field view for better diagnostic clarity.",
  "what_it_does": "This patent describes a way to capture and stitch together Optical Coherence Tomography (OCT) images of tissue samples that have irregular or uneven surfaces. It first creates a surface map of the sample to identify the highest and lowest points. By adjusting the scanning head's position based on this map, the system ensures that the imaging window stays aligned with the tissue's topography. Finally, it combines multiple individual scans into a single, wide-field composite image, using an entropy-based method to determine the best alignment between overlapping sections.",
  "what_it_does_not_cover": [
    "Does not cover imaging techniques that rely on non-OCT modalities like MRI or CT scans.",
    "Does not cover manual image stitching performed by a human operator without the automated surface-mapping logic.",
    "Does not cover systems that do not utilize a predefined surface map to adjust the scanning head position."

  "abstract": "Various embodiments of systems and methods are described herein for obtaining wide field OCT images and other types of image data from at least one portion of a sample. Various embodiments of systems, and methods are described herein for assessing a degree of differentiation for a second region of an OCT image of a tissue sample with respect to another first. Various embodiments of a sample container are also described herein for containing a tissue sample and maintaining the tissue sample in a defined orientation during imaging or handling.",
