摘要：
A device to acoustically couple a patient to an MR-HIFU system includes a first membrane configured to acoustically couple to an ultrasound window of the MR-HIFU system, a second membrane configured to acoustically couple to the patient at an exposed region overlying an ultrasound focus of the MR-HIFU system, a continuous side wall that includes a first edge sealed to the first membrane and a second edge sealed to the second membrane, and an acoustic coupling fluid contained within a closed internal volume defined by the first membrane, the second membrane, and the continuous side wall. The device also includes a heat exchange device operatively coupled to the acoustic coupling fluid. The device is configured to form an impedance-matched ultrasound coupling between the ultrasound window and the exposed region of the patient and is further configured to regulate a temperature of the exposed region of the patient.
