When larger than zero, the system enlarges the nominal delay between sub-spots while sonicating a
Macro-spot, effectively adding a “cooling time” between the sub-spots. Valid range is 0-60 seconds,
while the value in the default Treat protocol is zero.
◼ Separate A/P Layers
Set this field to ON and the system will plan Macro spot while separating between the anterior and
posterior layers of the sonication. During the sonication, the system will first perform all anterior
spots, then continue with the posterior spots. Value in the default Treat protocol is OFF.
◼ Under-Heated Energy Level
Sets a limit to the energy that the system can add when using the repeat under-heated regions
feature (see Section 7.4.6).
Optional values are Low, Mid and High. Value in the default Treat protocol is Low.
◼ Treatment Direction
Sets the direction in which the treatment advances. After each sonication, the system performs a
movement detection test on the next slice according to the treatment direction defined here.
Values are either apex to base or base to apex. Value in the default Treat protocol is apex to base.
◼ Use Urethra as LEDR
This field defines whether the Urethra drawing will be regarded by the system as a Low Energy
Density Region (LEDR). When set to ON, the system will automatically keep 3mm safety margins
around the drawing when planning spots (see section 6.7.6). When set to OFF, the Urethra drawing
will be visible and available as a handle while in Deformation Mode (see section 7.2.9).
Value in the default Treat protocol is ON.
When set to OFF, the Urethra drawing will be visible however the system will
NOT keep safety limits from it. Carefully examine the predicted dose location
of planned spots prior to performing a sonication.

◼ ROT Margin
Set the margins used by the system when automatically expanding a Target Volume to create a
Region of Treatment (ROT). It is possible to set different margins for AP/RL and for S/I expansions.
Values in the default Treat protocol are 10mm in AP/RL and 10mm in S/I.
