6. Place the posterior part of the imaging coil on the table, adjacent to the cradle’s hole.
7. Insert the coil's cable connector into the matching connector within the magnet bore.
8. Insert the tracking coils cable connector (attached to the cradle) into the matching connector within the
magnet bore.
9. Set up the probe as described in Section 3.2.
10. Place the phantom holder at the center of the coil.
11. Once attached to the Motion Unit, position the balloon in the middle of the phantom holder.
12. Lock the Positioner to the cradle and the Motion Unit to the Positioner.
13. Connect the probe cable pin to the Positioner.
14. On the Motion Unit controller, press on Enable + Connect.
15. On the Motion Unit controller, press on Enable + Home.
16. Cover the balloon with a generous layer of ultrasound coupling gel. Verify no bubbles are captured in
the gel.
17. Place the phantom gel on the phantom holder, over the balloon; make sure it is centered over the
balloon. Strap the phantom gel to the phantom holder.
18. On the Water System display, verify that it is in Treat mode and press on +15cc, several times if needed,
until the balloon creates proper acoustic interface with the phantom gel.
19. Place the anterior part of the imaging coil over the center of the phantom holder.
20. Set a landmark on the center of the phantom and insert the table into the MR bore. Ensure that nothing
hinders the movement of the table mechanism as it goes in and out of the scanner.
21. Insert the table to the MR bore.
22. Open new exam on the MR console and run Localizer scan
23. Start new treatment on Exablate workstation.
24. Perform a short treatment including at least 1 Macro-spot (with 3+ sub-spots). Check that the system
operates properly, that the spot is within 1 mm of the target location and that thermal dose is achieved.
25. Verify that the Region of Treatment (ROT) is reaching required ablative temperatures (> 65
o
C) during
Macro-spot sonication.
