Digital imaging colposcopy: basic concepts and applications
1Western Research Company, Inc., Tucson, Arizona.
Abstract:
The technique of colposcopy has changed little since the introduction of the green filter to improve viewing of vascular structures. However, the recent dramatic improvements in computer technology now make it practical to combine computerized image processing with colposcopy, which we have termed "digital imaging colposcopy." Image processing techniques permit contrast enhancement of features, such as white epithelium and abnormal vasculature. The digital colposcope allows rapid measurement of the cervical area involved with visible lesions, providing an improved means of following the progression of these lesions over time.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
