Dynamic spectral imaging: improving colposcopy.
PURPOSE Colposcopy occupies a key role in the prevention of cervical cancer by identifying preinvasive or invasive lesions. However, colposcopy is subjective and is responsible for 52% of screening failures. Dynamic spectral imaging (DSI) is based on the objective, quantitative assessment of the acetowhitening effect. This study compared DSI with colposcopy. EXPERIMENTAL DESIGN Women referred...
متن کاملComputed Diffusion Weighted Imaging (cDWI) for Improving Imaging Contrast
Introduction: Higher diffusion weighting (b-values) in diffusion-weighted imaging (DWI) is increasingly used to detect pelvic and bone malignancies. The low apparent diffusion coefficient (ADC) and longer T2 values of tumours make them visible at high b-values in comparison to the background tissue, which is largely suppressed. However, large b-values (especially > 1000 s mm) can cause severe i...
متن کاملImproving functional magnetic resonance imaging reproducibility
BACKGROUND The ability to replicate an entire experiment is crucial to the scientific method. With the development of more and more complex paradigms, and the variety of analysis techniques available, fMRI studies are becoming harder to reproduce. RESULTS In this article, we aim to provide practical advice to fMRI researchers not versed in computing, in order to make studies more reproducible...
متن کاملImproving underwater vision using confocal imaging
Confocal microscopy is a family of techniques that employ patterned illumination and synchronized imaging to create cross-sectional views of biological specimens. In this paper, we adapt confocal imaging to improving visibility underwater by replacing the optical apertures used in microscopy with arrays of video projectors and cameras. In our principal experiment, we show that using one project...
متن کاملImproving Underwater Imaging with Ocean Optics Research
Introduction: Underwater vision is vital to many Navy applications involving mine detection, diver visibility, and search and rescue. The ability to see better and farther has always been a central goal of underwater imaging projects. Unlike in the atmosphere, where visibility can be on the order of miles, the visual range in the underwater environment is rather limited, at best on the order of...
