5. You can move the treatment cluster with cells with the Move Treatment Cell Cluster button.
For hints and tips on placing the cells optimally, see the Application Guide.
If the cell you have placed is not treatable with the current transducer position, it will be marked
with a cross and the system issues a warning message. Select the cell and move it to another
location.
How to use markers and why ?
Add graphical markers to anatomy landmarks in planning images.
You can add markers at the Transducer Positioning stage and at any time after that. Select
Marker from the drop-down menu of the Add tool button.
Compare the location of the markers and the anatomical landmarks to detect patient movement
and image distortions.
The markers are visible in all planes.
Choose landmarks that you can also recognize in temperature map images.

6.6.7. Beam shaping

The beam shaping feature enables the user to reduce the intensity of the ultrasound field in
selected regions in the near field. These regions should be located close to the patient's skin, and
may include e.g. air bubbles, scar tissue, and skin folds. Identify the region where reduced
ultrasound intensity is desired by drawing an organ avoidance region (OAR) object around it. All
drawn OARs are shown in the Regions of Interest list in the Treatment Cell Planning page and
on the Replanning tab of the Therapy page.
