Mean diameter chart

The chart shows the trend of the mean diameter during the examination. The chart is divided into three or two parts, according to the study modality. You have basal (1), ischemia (2) and vasodilation (3) in FMD; ischemia is missing in vasodilation modality. In offline mode, a fourth part (4) may be present if the time length of the video is greater than the sum of the basal + (ischemia) + vasodilation.

The time length of the three (two) parts is set in the Timeline panel. You can set the timeline also by moving the three (two) vertical cursors that are present at end-baseline, end-ischemia and end-vasodilation.

Using the buttons at the top right (5) you can move up or down the chart, enlarge or reduce the vertical scale or restore the default view.
