Digital imaging colposcopy: basic concepts and applications.

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.
