    Faster 3-D imaging could aid diagnosis of cardiovascular, gastrointestinal disease

    Researchers have developed a faster way to acquire 3-D endoscopic optical coherence tomography (OCT) images. With further development, the new approach could be useful for early detection and classification of a wide range of diseases. The new method uses computational approaches that create a full 3-D image from incomplete data. In the Optical Society journal Applied Optics , the researchers report that useful 3-D images could be constructed using 40 percent less data than traditional 3-D OCT approaches, which would decrease imaging time by 40 percent. OCT is a biomedical imaging technique that has seen expanding clinical use in recent years ...

    1. Our tests verified that a greatly reduced amount of experimental data can be used to reconstruct reasonable 3-D OCT images...After we perform enough experiments to demonstrate that our probe and imaging method are useful for observing malignant features, our technique will be ready for clinical trials...This work is just one example of applying computational techniques to imaging applications...We expect that similar approaches may be helpful for improving the experiment designs and data acquisition for many imaging modalities.
