• Select the Confirm Rotary or Confirm Linear button in the probe
dialog shown right - this immediately adjusts the Actual position
to match the target position when the APD/RPD is not in use to
provide position feedback
Following any probe rotary or linear position manipulation, it may be desirable to shift the
monitoring planes to position the laser exit in a slice other than the center slice (the default).
In many situations, temperature elevations do not occur in slices proximal to the beam exit
position. However, temperature increases can occur in one and even two slices distal to the
beam exit position depending on how long the laser shot occurs. Therefore, the monitoring
slices can be adjusted for this purpose.
The adjustment is limited such that the beam exit position lies between the midpoint of the
proximal and distal slice of the three slice monitoring view.
The three slice plane lines shown above (red arrow) indicate the location of the MR
thermometry monitoring planes relative to the probe tip position. These can be adjusted from
the buttons within the
Monitoring Preference
area.
Center
: Aligns slice planes centered on laser exit position.
Deep
: Aligns slice planes distal to laser exit position.
Shallow
: Aligns slice planes proximal to laser exit.
WARNING: If at any point in the procedure it’s observed that the Software Rendered
Probe’s linear position or rotary orientation changes without user input, the Robotic Probe
Driver (RPD) should be visually inspected to confirm if its actual linear and rotation match
the values reported by the software. If a mismatch is noted, this is an indication that the
position sensors in the RPD are faulty. If this situation occurs, to prevent potential patient
injury the RPD should either be replaced or only be used in Manual Mode without robotic
assistance.
WARNING: If the patient head position changes relative to the head fixation device or the
initial MRI position set during the landmark procedure at any point during the NeuroBlate
procedure, the entire head must be re-scanned to include the AXiiiS (if applicable) using a
3D volumetric scan. This scan must be set as the master series with all other scans co-
registered to the new master series. Failure to reset master series may result in thermal
dose delivery to an unintended area potentially causing patient injury.
