is basically a surgical instrument similar to an electric microscope with a source of light that allows gynecologists to examine the vagina and cervix more clearly and under proper magnification.
The current rendition of the inserter device has a funnel-like, curved tip measuring approximately 2.6 cm in diameter, has a channel for insertion of a 2-megapixel mini-USB camera with LED illumination for the cervical image capture (as opposed to the 5-megapixel camera typically used with the Pocket Colposcope in the setting of standard speculum use), and can connect to a number of devices such as smartphones and laptop computers for image display.
Asiedu said the researchers are also seeking to modify the inserter to accommodate the original Pocket Colposcope with a 5-megapixel camera for better image quality.
Should the inserter and colposcope be validated in further studies, the potential benefits are numerous, she said, explaining that the device's potential for expanding access to screening are driven by its portability and low cost; the 2-megapixel camera currently used with the device costs about $54, compared with $20,000 for a standard-of-care digital colposcope.
The new release of the Document 20 guidelines advises on the latest advancements in cervical screening, and recognises the DySIS Colposcope for its financial and clinical advantages.
The DySIS Colposcope has been previously reviewed and recommended as being a cost effective and a clinically beneficial option by the UK National Institute of Health and Care Excellence in August 2012.
An evaluation of the photographi capabilities of representative colposcopes was performed.
Colposcopes, a comprehensive selected critical review.
Image clarity is always better when viewed through the colposcope. The provision of equal magnification is useful, and imperative in educational settings.
The high-resolution video monitors used in conjuntion with the colposcope provide a greater resolution than that of a typical television set.
Colpophotography is dependent on certain colposcope features and potential modifications.
Flash capabilities (with TTL exposure control) are highly recommended if photography is an important consideration in selecting a colposcope.
