The
following are the main steps for probe placement:
Image the ablation zone either by standard imaging technologies or direct
visualization.
Prior to placing the probes, set the probe exposure to the required depth of ablation
zone. Be sure to insert all probes to the ablation zone tissue depth.
Apply the probes to the ablation zone, reproducing the probe configuration on the
grid.
Verify that the probe placement is consistent with the probe configuration on the grid.
Edit the recommended probe layout to match the actual probe layout. Observe the
predicted ablation zone.
Connect probes to the corresponding electrode connector on the front panel of the
Generator. Verify that the connections are correct.
Select the UnDock Probes ratio button to remove probes from the Generator. This
feature will allow User to remove probes from the Generator without receiving an
error. If a Probe becomes unconnected when the Dock Probes radio button, the
system will send the User back to the Probe Selection Screen.
NOTE: It is very important that the probe number corresponds to the number indicated on
the Generator, so that its connector is plugged in so that the procedure performed meets the
planned procedure.
The
Hints Text Box
provides additional instructions as shown in Figure 5-42; i.e., "Use the
Dock Probes/UnDock Probes radio buttons to disconnect and re-attach probe(s)."

5.1.5 Pulse Generation Screen
The
Pulse Generation
screen (see Figure 5-43) is the screen where the ablation is
delivered. It consists of two sub-screens, the
Procedure Parameters
screen, which is the
default screen, and the
Result Graphs
screen (see tabs in the upper left of the screen). The
lower sections of the screen do not change when moving from the Procedure
Parameters
screen to the Result Graphics screen. An ablation procedure can be started and aborted
from either screen. The User can move between the screens during the ablation procedure.
