Question special

As our discussion is drawing to a close, I'd like to ask the authors and experts to give their opinions on next steps in the field of FUS for various treatments. Granted, Dr. Tierney and Dr. Elias spoke of the technical refinement of the procedure and the need for trial comparisons between FUS and DBS, Dr. McDannold and Dr. Tierney mentioned further research in studying the properties of individual cranial morphometry, and Dr. Ghanouni spoke of applications of FUS to treat tumors in other settings. To our authors and experts: what are the greatest challenges that current clinicians and researchers are facing to advance treatment and direct care in the areas discussed?
