Use the Compare tool to display two enlarged copies of an image side by side and assess the effect of changing the window level or other presentation options.
To compare image presentations
From the Image area context or top toolbar, click Compare.
Or, if using the context toolbar text menu (Ctrl + right-click), select Magnify/Pan > Compare.
Click an image of the series to clone.
The Compare window opens, displaying the original image on the left and a clone on the right. If more than one Image area monitor is available, the Compare window opens on the monitor next to the one you have clicked on.
Perform any of the following actions in a Compare window:
Select appropriate tools from the top toolbar or context toolbar and apply them to the original or cloned image. Only changes made to the original image can be saved.
Move the window by dragging the title bar.
Navigate through images with the Page Up or Page Down keys.
Navigate though series with the Previous and Next buttons.
You cannot resize the Compare window.
To close the window, press Alt + F4 or click Close.
Or, to automatically close the Compare window, cycle to another patient's studies. (You may be prompted to save any changes made to the original image.)
