Use image visualization tools
Note
You can right-click (or touch and hold) a viewport to access the tools. You can also customize the toolbar (see Change tool preferences) and assign tools to mouse buttons, keyboard shortcuts and touch gestures (see Change mouse, keyboard and touch preferences).
After using a tool, your changes are saved unless you select Reset (to remove changes from all images in the series), Reset Current (to remove only the changes for the interaction currently selected) or Annotations > Delete Last/Delete All (to remove changes from current image) before closing the study.
Note
Some tools are only available for specific modalities and views.
