TREATMENT STAGE
Manual Part Number
◼ If there is a need to stop the sonication process, press the Stop Sonication button.
◼ Monitor the temperature maps during the sonication. If an unexpected thermal
rise or dose is found outside the target location, stop the sonication.

6. After the sonication, the Thermal Evaluation screen opens with the actual thermal dose contours
overlaid on the image (see Figure 7-4). Review the results as described in Thermal Dose Verification
(see Section 7.4.4).
◼ Monitor the thermal rise and dose buildup at the target location, and at the
relevant pass zone with special attention to the rectal wall.
◼ In case temperature on the rectal wall exceeds 75°C, press the Stop Sonication
button and reduce the energy of the following sonication.
◼ The geometric verification procedure must be repeated if the thermal hot spot is
not noticed on thermal imaging sequence during treatment.

7. The system will automatically initiate Current Anatomy Scans on the MR.
8. The system will notify the user in case the targeted area was not fully covered with dose (above pre-
defined threshold).
9. If required, choose to repeat the sonication using the Repeat Under-Heated Regions (refer to
Section 7.4.6)
10. Click to accept the measured dose and return to the Treatment Main Screen.
After continuing to the next sonication, the operator will NOT be able to edit the
Accumulated Measured Dose of previous sonications. Use Dose Polygons in case only
part of the measured dose should be accumulated.
