    6. Multivendor Spectral-Domain Optical Coherence Tomography Dataset, Observer Annotation Performance Evaluation, and Standardized Evaluation Framework for Intraretinal Cystoid Fluid Segmentation

      Multivendor Spectral-Domain Optical Coherence Tomography Dataset, Observer Annotation Performance Evaluation, and Standardized Evaluation Framework for Intraretinal Cystoid Fluid Segmentation
      Development of image analysis and machine learning methods for segmentation of clinically significant pathology in retinal spectral-domain optical coherence tomography (SD-OCT), used in disease detection and prediction, is limited due to the availability of expertly annotated reference data. Retinal segmentation methods use datasets that either are not publicly available, come from only one device, or use different evaluation methodologies making them difficult to compare. Thus we present and evaluate a ...

    8. Beyond Better Clinical Care: Optical Coherence Tomography's Economic Impact

      Beyond Better Clinical Care: Optical Coherence Tomography's Economic Impact
      The optical coherence tomography (OCT) industry has grown dramatically in its first 25 years, and while the positive effects on patient clinical care are the most important measure of OCT's success, its contributions to the economy in jobs, tax receipts, and healthcare savings are also noteworthy. The field of optical coherence tomography (OCT) has grown dramatically since its discovery in the early 1990s. The commercialization and growth of OCT ...
