Tissue thermal interactions (such as coagulation) are not governed by the temperature of the tissue alone. The duration for which the tissue is exposed to any given temperature is also of critical consequence. The NeuroBlate System uses non-invasive, near real time MRI thermometry to monitor temperature change and duration.
Note: The MRI system will revert to the default configuration at the end of the NeuroBlate procedure. CAUTION: Do not enable the real time data transfer interface prior to this point in the workflow.
Page 115
CAUTION: For Siemens MRI software version 19, the values for the Switches Menu should be reset to their original values at the end of the NeuroBlate procedure following the same procedure outlined on pages 105 – 106 to prevent suspending the MRI software requiring an MRI system reboot to clear.

Hospital network and directly connected to the NeuroBlate Main PC forming a direct peer-to- peer network connection. In this case, both the NeuroBlate system and the Philips MRI will be disconnected from the hospital PACS network during treatment monitoring. The MRI connection to the PACS network can be restored following treatment monitoring once real time data transfer is no longer necessary.

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.
Page 123
WARNING: The thermal monitoring planes must be centered at the middle of the FullFire laser emission area to adequately capture thermal dose. WARNING: Creating a greater than 7.5mm radial ablation may exceed the NeuroBlate System’s ability to monitor thermal dose in the longitudinal direction.
80469 Rev D – Nov 16, 2018 8.8.2. Thermal Sequence Prescription on the MRI CAUTION: MR Thermometry Data. The MR data must use the NeuroBlate System defined sequence parameters for temperature measurement. This includes use of a specific GRE sequence preinstalled on the target MRI system. The only modifications allowed are position, orientation and phase encode direction depending on the location.

WARNING: Treatment slice orientation and position must match the treatment planes shown in the views. The MR pulse sequence parameters other than orientation and position must not be changed and must adhere to the requirements for NeuroBlate treatment. WARNING: Do NOT power ON the Interface Platform during MR imaging. Image quality may be compromised.

NeuroBlate® System Instructions for Use 80469 Rev D – Nov 16, 2018 Note: Selecting the Reset Mask button will clear any masked regions and begin the noise and temperature masking stage upon the next measurement. It’s similar to beginning at measurement 1 in a new acquisition but does not require a reset of the current MR acquisition.

NeuroBlate® System Instructions for Use 80469 Rev D – Nov 16, 2018 CAUTION: During treatment: If there is concern for cranial bleeding, the user may consider acquiring blood-sensitive (GRE) MRI imaging in between laser shots at intervals throughout the procedure. This type of scan should be executed on the MRI only when linear or rotary probe motion is NOT active.

• Stop thermal delivery by releasing the laser foot pedal • Allow MRI to continue acquiring the NeuroBlate Thermal Monitoring Sequence to allow all heated tissue to return to baseline temperature. For tissue adjacent to the probe, this may require up to 120 seconds. Tissue further away from the probe may take longer to return to baseline temperature.
Page 148
NeuroBlate® System Instructions for Use 80469 Rev D – Nov 16, 2018 WARNING: Failure to allow all heated tissue to return to baseline temperature prior to stopping MR acquisition may result in inaccurate calculation of thermal dose levels which may lead to patient injury. Maintain MRI acquisition (which ensures internal probe cooling) to allow tissue next to the probe to cool to the baseline temperature which may require up to 120 seconds.
Page 149
NeuroBlate® System Instructions for Use 80469 Rev D – Nov 16, 2018 Throughout the procedure, use the pixel temperature query tool under the Temperature Point heading in the right menu to monitor brain temperature in the area of thermal monitoring (see Figure 8.8.3.34)
NeuroBlate® System Instructions for Use 80469 Rev D – Nov 16, 2018 Once all desired treatment slices and angular positions of the probe have been used to optimize the desired coagulation result, the user can select end treatment at any time. Any running MRI acquisition should be stopped after all tissue returns to baseline temperature.
