1. Click this button and select Macro spot. Add the spot at the desired ROT slice by clicking
inside it. Spots can be added on the Current Anatomy strip only.
NOTE
Clicking at the right or left half of the ROT slice polygon will affect the direction in which
the Macro spot is planned and executed.
[N-41]
2. The system will automatically plan an optimized Macro-spot that covers the entire ROT slice while
taking all LEDR limitations into consideration.
3. Macro spots can be edited by:
◼ Selecting the entire Macro-spot and dragging it. All sub-spots inside the Macro-spot will be dragged
as well.
◼ Selecting the entire Macro-spot and changing its Energy. This will affect the Power of all sub-spots
while keeping the same total Duration.
◼ Dragging, deleting and changing Energy is also applicable on specific sub-spots. Select the desired
sub-spot and perform the required operation.
◼ To change the Power of a Macro-spot without affecting its Energy (but rather affecting its Duration),
change the Power setting in the Treatment Protocol (see Section 6.8).
4. Following each Macro-spot editing, the system will re-predict and re-validate the Macro-spots (see
Section 7.2.7).
5. Click the Sonicate button to apply the ultrasound energy; the system transfers the
sonication location to the MR.
6. Monitor the following during the sonication:
◼ The evolving temperature rise and dose during sonication. Pay special attention to the temperature
on the rectal wall.
◼ Patient movements, by observing the Rectal Wall and Prostate Capsule drawings on the updated
MR anatomical images.
◼ The real-time images to ensure coupling and verify no air bubbles entered the interface between the
balloon and the rectal wall.
