Claim 17:
18. A system for transcranial magnetic resonance (MR)-guided focused ultrasound, the system comprising:
a transcranial ultrasound transducer configured to apply ultrasound radiation to a head of a patient, the transcranial ultrasound transducer comprising:
a housing that is concave, the housing defining a cavity comprising a bottom opening that is configured to receive the head of the patient; and
a transducer surface within the housing;

an antenna that is configured to reflect radio frequency (RF) waves; and
a support configured to be connected to an outer rim of the transcranial ultrasound transducer and configured to suspend the antenna within the cavity, wherein:
when the head of the patient is received within the cavity the antenna is between an inner surface of the housing and a top of the head,
the antenna is passive and does not form an electrical connection, and
the antenna is positioned within the cavity between the inner surface and the bottom opening and is configured to reflect RF waves entering the cavity from the bottom opening before the RF waves reach the inner surface.
