Zoom In on a Portion of an Image

You can use Smart Zoom to increase the magnification and window level for a selected area.

Place the Smart Zoom box on the area you want to magnify. Select the box, then use the Zoom tool to change the magnification within the box. You can also change the Window Level within the Smart Zoom box.

Compare Images

You can use Smart Zoom to compare two series. To overlay a series on top of another series, drag a series from the Series panel or the patient timeline into the Smart Zoom box. You can also drag a preset into the Smart Zoom box.

The study date for the overlay series is shown in the Smart Zoom box (if this date is different than the study date of the underlay series).

OptosAdvance automatically registers the overlay series to the underlay series when one or both of the series change (for example, when you scroll through the images in the overlay or underlay series). A green circle in the bottom-left corner of the Smart Zoom box indicates that auto registration was successful; a red circle indicates that it was not successful.

  2. To stop the animation, click the Pause button in the bottom right corner.
