Mark Location

Outline a region of interest with an ellipse and automatically add a line segment that measures from the edge of the ellipse to a landmark such as a nipple.

Use the Mark Location tool in mammography studies to outline a region of interest with an ellipse and automatically add a line segment that measures from the edge of the ellipse to a landmark such as a nipple. The tool provides a number of labels (such as Microcalcification, Asymmetry etc.) that you can select from that will be used to label the measurement. The measurement can then be saved as a Key Image or Presentation State.

NOTE: The Mark Location tool cannot be used in Advanced Visualization modes.

The Mark Location tool may need to be added to your toolbar or context menu. For more information, see Customize the toolbar or Customize the context menu or contact your system administrator.

On the toolbar, click and select a label for the measurement.
Place your cursor near the region of interest, left-click to start the ellipse and left-click again to end it.
The line segment will be drawn automatically as soon as you move the cursor. Left-click to set its end point.

To discard the measurement before it is completed, press the Esc key.

Edit a measurement

Click the measurement to select it and do any of the following:
- To resize the ellipse, drag the handles on the edge of the ellipse.
- To reposition the entire ellipse, drag from the center of the ellipse.
- To resize the linear measurement, drag the handle at the end of the line segment.
- To reposition the entire measurement, drag the handle in the center of the line segment.
- To reposition the measurement label, drag it to the desired location.
