5.7.3. Overlay tools
The overlay tools assist you during the planning and monitoring of the treatment. They allow the
display of objects related to treatment planning and monitoring, such as cells, transducer positions,
or temperature maps on top of a planning image. Some overlays also allow adjustment graphically.
Several overlays can be displayed simultaneously.

Shows the transducer beam path. Visualizing the beam path helps in
avoiding organs in the near and far field. The position of the
transducer can be graphically adjusted by dragging from the handles
on the transducer beam centerline.

the current transducer position.
Shows the slice position in the imaging volume.
Shows the temperature rise as a colored overlay and the color-coded
temperature scale on the right side of the image window. The tool
button has a context menu, in which you can choose between filtered
and raw data temperature maps.
Shows the dose as two contours around the heated area. The white
contour shows the area in which the heating was sufficient to produce
necrosis. The orange contour shows the area that was heated but not
enough to produce necrosis.

with the Measure tool.
With cell visibility, you can select how the treatment cells are shown.
Display all cells, no cells, the cells on the active level, the cells in the
current target volume, current transducer position, or current cluster,
or display only the sonicated or pristine treatment cells.
