3. Click the Sonicate button to apply the ultrasound energy; the system transfers the
sonication location to the MR.
4. Monitor the following during the sonication:
◼ The evolving temperature rise and dose during sonication. Pay special attention to the temperature
on the rectal wall.
◼ Patient movements, by observing the Rectal Wall and Prostate Capsule drawings on the updated
MR anatomical images.
◼ The real-time images to ensure coupling and verify no air bubbles entered the interface between the
balloon and the rectal wall.
◼ Spectrum signal during the transmission of the acoustic energy.
◼ 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.
◼ If an unexpected thermal rise is found outside the target location, stop the
sonication.

5. After the sonication ends, the Thermal Evaluation screen opens (see Figure 7-4).
6. System automatically initiates Current Anatomy Scans on the MR (in the background). The updated
strips will be displayed when returning to the Treatment Main Screen (see Figure 7-1).
7. Check whether there has been patient movement by observing the location of the Rectal Wall,
Prostate Capsule and LEDR contours on the Sonication Anatomical images.
8. If required, use this button to draw Measurement Polygons to evaluate the temperature
rise.
9. Analyze the results and compare the size of the obtained (measured) dose with the planned
(predicted) dose:
