Measurements
Undo Points
Remove the most recent contour points while tracing area, volume, or VTI measurements.
Undo Points
HeartLab allows users to remove recently placed contour points while tracing measurements. This can be used to refine contours without restarting the entire measurement.
Undo points are available during area, volume, and VTI tracing workflows.
Applies to
- All users can create measurements, however users with the Viewer only role cannot save measurements.
Measurements can only be saved if the study does not already have an approved final report.
Steps
- While tracing, move the cursor back toward the previous point to reveal the undo marker (Red Cross).
- Select the undo marker to remove the previous point.
- Repeat as needed to continue refining the contour.
- Alternatively, select Redo to restart the measurement.
Use incremental point placement when tracing low-contrast borders to make corrections easier and more precise.
