Dynamic curves
After Dynamic Imaging, users can also review the dynamics of the acetowhitening response of the tissue at
any location on the cervix, by pressing “Show Graph”. This displays a graph on the upper left part of the display
(but can be moved around the screen to a convenient location), where the vertical axis represents the
acetowhitening intensity and the horizontal axis represents the time since application of acetic acid.
Examination Screen (DYSISmap & graph shown)
By touching the screen at different sites on the cervix using the image on the touch screen, it is possible to
view the response at different sites. This tool can facilitate the review of the acetowhitening phenomenon at
different locations, simply by monitoring the variations in acetowhitening intensity (curve height) over time.
This tool is available during acetowhitening when Ultra is being used. When TRIAL mode is switched on this
function is only available after the map has been calculated and viewed.
