Ablation Zone Voids: The Black outline inside the ablation zone. Depending on the
location of the probes and the voltage selected, the void may be large or small
(see Figure 5-25). In some cases, the void may be a single Black dot within the
Ablation Zone. Move the probes or increase the voltage to fill in ablation zone
voids.

The numbered Green circles are the Probes. The numbers correspond to the
probes’ connection port on the Generator. The User may click on a probe to
display probe location relative to other probes and the ablation. The Probe
location can be changed by dragging and dropping each probe. Ablation size
and shape will be automatically updated to the Procedure Spreadsheet. Once
selected, probes can be moved in 1 mm increments by using the Up, Down, Left,
and Right arrow buttons on the keyboard.
Overlapping Ablation Zone: The system allows the User to save an ablation so that
if a part of the lesion was missed, User can go back to the Probe Placement
Process screen to see where the procedure was completed. After the first
ablation, click on the back button to go back to the
Probe Placement Process
screen to see the completed Ablation Zone . This will be the grey area with the
red hash marks. The User can then move the probes to completely cover the
lesion. See the following examples showing overlapping ablation zones in Figure
5-26 and Figure 5-27, noting the treated area and area missed.
