3.5. Patient Release
At the end of the treatment, release the patient as follows:
1. Exit the treatment in the Exablate workstation.
2. Take the cradle out of the MR bore back to home position.
3. On the Motion Unit controller, press on Enable + Home. This will bring the transducer back to its home
position, which is the safest position for extraction.
4. On the Water System display, press Extract. This will pause the circulation, drain the balloon back to
the initial insertion volume, and will move the water system display to the Home screen.
5. Release the large hand screw that fixes the Positioner to the cradle and retract the entire Positioner
along with the probe backwards from the patient.
6. Release the hand screw that fixes the Motion Unit to the Positioner and lower the probe until it lies
safely on the cradle.
7. Disconnect the imaging coil and the tracking coil cables from their connectors within the magnet bore.
8. Lower the table and carefully remove the patient from the table.
9. Remove all single-use items from the probe and discard as per hospital policy.
10. Perform cleaning and high-level disinfection of the water system (see Appendix C for details).
All single-use items (e.g., disposable shell assembly, drapes and covers) MUST be disposed
of properly after each use according to the institution rules and procedures.
