The table below represents the color code used to document the tissue acetowhitening dynamics as depicted by
DYSIS Ultra 2.0. This color assignment is based on combining the intensity and duration of acetowhitening over
the time period of the dynamic imaging procedure.

Dynamic Curves
After Dynamic Imaging, users can also review the dynamics of the acetowhitening response of the
tissue. The graph is displayed on the right side
Fig). The vertical axis represents the acetowhitening intensity and the horizontal axis represents the time since
application of acetic acid.
By touching the screen at different sites on the cervix, it is possible to view and compare the response at
different parts of the cervix. This tool can facilitate the review of the acetowhitening phenomenon at different
locations simply by monitoring the variations in acetowhitening intensity (curve height) and persistence. This
function is only available after the map has been calculated and viewed.
The histogram represents the count of each color on the map in a logarithmic scale.
