    1. Intraoperative optical coherence tomography for assessing human lymph nodes for metastatic cancer

      Intraoperative optical coherence tomography for assessing human lymph nodes for metastatic cancer
      Background Evaluation of lymph node (LN) status is an important factor for detecting metastasis and thereby staging breast cancer. Currently utilized clinical techniques involve the surgical disruption and resection of lymphatic structure, whether nodes or axillary contents, for histological examination. While reasonably effective at detection of macrometastasis , the majority of the resected lymph nodes are histologically negative. Improvements need to be made to better detect micrometastasis , minimize or eliminate lymphatic ...

    2. Real-time Imaging of the Resection Bed Using a Handheld Probe to Reduce Incidence of Microscopic Positive Margins in Cancer Surgery

      Real-time Imaging of the Resection Bed Using a Handheld Probe to Reduce Incidence of Microscopic Positive Margins in Cancer Surgery
      Wide local excision (WLE) is a common surgical intervention for solid tumors such as those in melanoma, breast, pancreatic, and gastrointestinal cancer. However, adequate margin assessment during WLE remains a significant challenge, resulting in surgical reinterventions to achieve adequate local control. Currently, no label-free imaging method is available for surgeons to examine the resection bed in vivo for microscopic residual cancer. Optical coherence tomography (OCT) enables real-time high-resolution imaging of ...

    3. Computational high-resolution optical imaging of the living human retina

      Computational high-resolution optical imaging of the living human retina
      High-resolution in vivo imaging is of great importance for the fields of biology and medicine. The introduction of hardware-based adaptive optics (HAO) has pushed the limits of optical imaging, enabling high-resolution near diffraction-limited imaging of previously unresolvable structures 1 , 2 . In ophthalmology, when combined with optical coherence tomography, HAO has enabled a detailed three-dimensional visualization of photoreceptor distributions 3 , 4 and individual nerve fibre bundles 5 in the living human ...

    5. Computational adaptive optics for interferometric synthetic aperture microscopy and other interferometric imaging

      Computational adaptive optics for interferometric synthetic aperture microscopy and other interferometric imaging
      Methods for correcting for aberrations in the image or three-dimensional reconstruction of a sampled region obtained by broadband interferometry. The sampled region is illuminated with a broadband beam of light, and light returned from the sample is detected, along with a reference beam, in order to derive an interference signal for pixels of a volume spanned by wavenumber and axes transverse to the beam propagation direction. An optimization procedure is ...

    6. Segmentation And Correlation Of Optical Coherence Tomography And X-RAY Images For Breast Cancer Diagnostics.

      Segmentation And Correlation Of Optical Coherence Tomography And X-RAY Images For Breast Cancer Diagnostics.
      Pre-operative X-ray mammography and intraoperative X-ray specimen radiography are routinely used to identify breast cancer pathology. Recent advances in optical coherence tomography (OCT) have enabled its use for the intraoperative assessment of surgical margins during breast cancer surgery. While each modality offers distinct contrast of normal and pathological features, there is an essential need to correlate image -based features between the two modalities to take advantage of the diagnostic capabilities ...

    9. Real-time in vivo computed optical interferometric tomography

      Real-time in vivo computed optical interferometric tomography
      High-resolution real-time tomography of scattering tissues is important for many areas of medicine and biology 1 , 2 , 3 , 4 , 5 , 6 . However, the compromise between transverse resolution and depth-of-field, in addition to low sensitivity deep in tissue, continues to impede progress towards cellular-level volumetric tomography. Computed imaging has the potential to solve these long-standing limitations. Interferometric synthetic aperture microscopy 7 , 8 , 9 is a computed imaging technique enabling high-resolution volumetric ...

    10. Intraoperative assessment of tumor margins with a new optical imaging technology: A multi-center, randomized, blinded clinical trial

      Intraoperative assessment of tumor margins with a new optical imaging technology: A multi-center, randomized, blinded clinical trial
      Background: Partial mastectomy is the most commonly performed procedure for invasive breast cancer and is associated with a reexcision rate commonly ranging from 20% to 40% in the literature. This high rate of reexcision is associated with significant additional cost (estimated over $4,000 per reexcision) and lower quality outcomes. Optical coherence tomography (OCT) is a high-resolution imaging technology that images tissue structure with micron-scale resolution on the same scale ...

    12. Guide-star-based computational adaptive optics for broadband interferometric tomography

      Guide-star-based computational adaptive optics for broadband interferometric tomography
      We present a method for the numerical correction of optical aberrations based on indirect sensing of the scattered wavefront from point-like scatterers (guide stars) within a three-dimensional broadband interferometric tomogram. This method enables the correction of high-order monochromatic and chromatic aberrations utilizing guide stars that are revealed after numerical compensation of defocus and low-order aberrations of the optical system. Guide-star-based aberration correction in a silicone phantom with sparse sub-resolution-sized scatterers ...
