The multispectral digital colposcope (MDC) is a specialized lightsource and imaging device mounted on a custom-made colposcope that acquires a sequence of fluorescence images. This version of the MDC incorporates an upgraded light source, and updates the firmware and the user interface. This results in shorter acquisition times and improved image and spectrum quality control. The MDC also consists of a point probe that is used to take detailed light measurements (call spectroscopy) from smaller regions of the cervix. The goal of the study is to see whether the MDC can perform better than standard methods in detecting cancerous or pre-cancerous abnormalities of the cervix.
